Which engine & what horse-power

[CPT Haddock]

I have the 26m, which is doing fine however I would like to go just that tad bit faster, the 50hp does the job well but lets think better, below is a table of specs that Im considering, has anyone setup higher horsepower and what were the results?

any thoughts on this would be appreciated as well

Evinrude
Horsepower 50 90 115
Kilowats 37 67 86
Weight 109 167 167
AMP 75 75 133
Watts 1100 1100 1800

53% heavier 53% heavier
80% More Power 130% More Power
78% More Charging

How far do you want to go with your fuel?
How much punishment do you want to do to the boat?

The faster speeds can be really hard on the boat and it can get very wet. Your choice.

There is many threads discussing this.

Good luck and make stronger as much as you can. Check standing rigging before every cruise.

Hi

I would get the new Honda 90 4S EFI.

I have an E-tec 90. So far, less than 10 hrs but it is a great match for the M. I use a 14 X 11 prop that gives good speed (25 mph) and good power at all speeds. If you want to increase speed you better hold on. A 14 X 13 may give a little more top end speed but I am very pleased with what I have.

I liked the new Honda 90 EFI but none of the dealers in my area had a delivery date and I needed a motor. Maybe you can contact Sorcha, near Brisbrane. He has a etec and had some problems but I think (hope) those have been resolved.

This is a picture of my 90 installed. It will hit the seat in the down position if you tilt it all the way up but that is not necessary for travel. It has a built in brace that needs a lot less travel.



There are a lot of good motor choices out there.

Too true Mac Ziggy.

... but I would have to say, the waterbeggo needs a big motor to do the job.

Unless sailing is your primary focus of course, then having a 50 is enough to get out of those sticky situations and is able to empty the ballast tank with ease.

Nice pics

[CPT Haddock]

thanks for the information and the photographs, very helpful

Im now gong to measure up the motor head of the 115hp and see how it compares to the 90

I do a fair bit of sailing but when one needs to cover ten or so miles to get to the pub for lunch well, then horses are needed and the champers keeps the admiral happy (wife)

thanks for the feedback

your numbers are not correct:
the ETEC 90 and 115 have different powerheads.
the 90 weighs (dry weight) 320# / 145 kilos.
the 115 weighs 369# / 167 kilos.

the New! Honda 90 - 4 Stroke weighs 359#.

I would check the link below about comparisons. it makes you think a little. Im a 2 stroke fan I have had outboards my whole life. I own the Suzuki 50 four stroke and like it. But the 60 etech on some of my Buddy's macs will blow mine away. Now weight is important the less you have the more performance so my choice for the mac at least untill I see a better outboard is the e tech 90 white (saltwater version) looks better on the mac. I just finished rebuilding my 50 merc carbs on my whaler the motor is 21 years old and now runs like it just came out of the box. It does smoke and it does foul a plug or two in a season but it runs and runs and runs.

A two stroke that does not smoke, weighs less, doesnt foul plugs would be my choice for the mac. in fact if I wanted to put up with the smoke and smell I would install a 90 2 stroke merc from the late 1990's.

the etech 90 looks really good to me. I have had my eye on it for a year or so and I like the idea that Evinrude went the clean 2 stroke route as opposed to fourstroke. Theres a reason outboards were always 2 strokes in the past and that is less parts and more power per pound.
this hasnt changed at all. My guess all the outboard manufactures will (once they recoup from the 4 stroke) will go evinrude route some day.
That is if evinrude e tech lives up to expectations over time. But check the link below and see some interesting (one sided) facts.

Give the link from my last post a little time to load.....check challenges then check it out. I like the tug of war the best/////

again four strokes are good at idle dont smoke, and get better fuel economy. But what they dont do as I have seen is, quieter, the fourstroke on my boat is as loud as any two stroke I ever owned at full throttle.
By putting a smaller engine on our boats we will always be at full throttle to get on plane. But a larger engine at half throttle to do the same job is not as loud no matter what type engine. the bigger engine also gets about the same gas mileage as my Suzuki when going any distance using less throttle. The Honda looks good but its still a four stroke and new this year.
I dont think I would want the first year production on any outboard unless your a pro bass fisherman that changes his outboard every two years.

thats why Im waiting on the e tech 90, one more year for me and its on the mac it goes....

[Boblee]

We only run an e-tec 50 but am very impressed with the absolute lack of smoke except for the first ten hours and the economy.
I have always been a 4 stroke fan but the e-tec is quieter, cleaner and more economical with fuel (and oil if you factor in services) at all speeds and also has more grunt out of the hole.
It took a bit to go against all my old theories but could not be happier unless I put a 90 on.
The Tohatsu TLDI looked good but I am happy now with less services to worry about on a long trip re warranty.

[They Theirs]

Interesting?
BWY Todd tested many engines, and posted the reason they were going to a 4-stroke, were because of the considerable noise of the 2-stroke (Said his wife could not hear the expensive sterio) and lack of fuel economy….

Recent and past posts of increased oil consumed with more fuel than the manufacturers claims…plus other related problems.

I like the light, small profile, quiet 4-stroke with enough power for reasonable boating, only exceed by the venerable Nissan/Tohatsu lightweights of years past for their weight advantage…. someone soon will justify an “Allison” engine, because “nothing else is bigger, faster, quieter, or gets better fuel economy at light speed!”



We love the bolt on heavy heavy-weights with skill and ability to throttle down over the biggest chop without tearing up the boat?…especially opposed to those who’ve acquired skill enough to enjoy sailing when the breeze is up, without 400+ lbs. dragging the transom down.

Aya 16…you’re not going over to the dark side???


We all know it takes considerable fuel/oil mix for proper lubrication of 2-cycle engines

Chain saws and lawn mowers…. 16:1
Early outboards………………...24:1 and 36:1
Later outboards……………….. 50:1
Newer and today’s 2-strokes…100:1 and leaner…….. Hmmm?

[aya16]

yes dark side, No I have a four stroke and the idea sounds great just really disappointed in the hype of the four stroke. Although I only have a 50 (Which I dont recommend to any Mac owner) 60 and above is what I would put on. The 50 just doesnt get the boat in the sweet spot unless lightly loaded. And we all over time are beyond lightly loaded. Plus running an engine at max throttle all the time (for me, crossing to Catalina) isnt that good for the engine, let alone the noise. BWY recommends a seventy and really like the performance. But they are running a fourstroke 70 I think.
The weight is more than a 2 stroke 90 and in some cases the 70 four stroke is the exact same engine as the 90 in every way except tuning.

BWY also said they dont trust the etech, or something to that effect and dont run them.

Burning oil isnt a problem with the etech if you just want to count how much oil you burn against how much oil you toss away with every four stroke engine oil change over a year.

Th etech contrary to Evinrudes claims do break in the first few hours of service by using double the oil in the mix for awhile. But then goes up to
normal burn rate later.

Two strokes that are allowed on our lakes that comply with epa are very state of the art. My concern is how bullet proof that tech is. Time will tell
and Im watching. But with a five year warranty they take some of the worry out of owning it.

The Mac needs more than a fifty, Thats a fact I have one of the best four strokes (claimed) on the market as far as power and weight goes.
But really need to push it hard to get on plane. The etech 60's I see are doing the job nicely with out pushing the engine to hard, and are doing it without valves, cams, drive chains and other four stroke related stuff.
and the 2 stroke was, is made to run at high rpm all the time.

Gas millage is equal or better with the etech and my suz. There is no smoke It will idle all day like a four stroke and just plain has the ommmphh to make the Mac perform.

My logic is this: If the sixty etech does a good job on a heavy loaded mac then a seventy will do better, But the seventy is the exact same engine as the 90 so I want the 90, not to go 26 mph but it can. But to cruise at 18-20
without trying real hard. Plus that 90 etech looks sooooo pretty sitting on the Mac. (white)

CPT:
Do you have a big foot on your 50 hp?
We have a 50HP BF Merc. We can break 15 mph easy and have hit 18 mph and always with full ballast. Have no idea how fast she would go without ballast weight. Only time my Merc is loud is WOT.
Then again if your looking for speed you really need a speed boat They put IO's on pontoons but you can only get so much getup and go from a Hull design.

Did anyone look at the videos on Evinrude site I posted the link too?
No comments so far, check out the tug of war...
