auxilliary motor mount

[saltybrain]

hi,

i am keen to install an auxilliary motor on my 1999 26x, as i intend to make the crossing from malta to sicily this season, 55nm distance. I know its not much distance but with land just out of sight i would feel better with a backup motor (altough the sails count as a motor too ). for piece of mind.

what im thinking is a 9.9hp 4-stroke, are there any special considerations i need to think of ?
for example;
- do i need a special shaft length ? or is that compensated for in the bracket used
- what bracket to use ?
- is 9.9 enough or too much, as it is heaver than a 4 or 5 hp. will it affect balance much.
- stearing : it is locked 'straight' and the rudders are used is that how it works ? but it would be installed to one side, so i guess there would be a tendency to turn so it would be annoying to use (but im sure if it needed using id be all to happy to compensate!!)

any thing else i should consider with an auxilliary installation ?

(i am new to the mac26x, this is my first season)

thanks!

I have a fixed bracket that hold my 2.5 hp Susuki 15 inch shaft for my inflatable. I can tow my boat in calm waters with dingy tied off on Port or Starboard side.
Even if you used a 20 inch shaft on a adjustable bracket, it would still wouldn't be long enough as you would need it at least 4 inches lower than your cavitation plate, other wise you would do more cavitation if water line was 1 inch higher than the Cavation plate for normal installed engines.
The Mac.X has high free board and when engine is lowered the angle of throttle handle would be about 20-30 degrees from vertical.
A 6 hp Nissan weighing 55 lbs is plenty of power to move you at 3-4 knots in calm waters and any wind above 3-4 knots you can sail.
Having a outboard for dingy use and emergancy power does both.
Do you have tow insurance in your area?
Here is a photo of my bracket without outboard, my outboard with 15 inch shaft clears the water by 4 inches and just hits on a 15 degree heel.

The Mac.X does not have enough room to mount anything larger than the Nissan and it is very difficult mounting the bracket as there is no access to inside transem for putting your nuts on bolts and have to drill a 1-1/2 inch hole at transem centered at middle of bracket and another one at side as there is a fiberglass wall you need to go thru to reach the inner bolts with a very thin needle noze lock plyers to hold the nuts. Very time consumeing and a lot of patiance.
You put a plastic cover over the holes sealed with 3m 4200, these covers can be bought at Blue waters.

Hi David,

Thats great, thanks for the info : beautiful boat btw!

so just to be clear, those other mac26x's iv seen with the auxiliary bracket is really just to hold the dingy motor and not for powered use on the mac itself ? iv seen a few in photos even here in these forums.

makes sense though

cheers

I have a Fulton bracket that allows it to be lifted up out of the water when not in use. I have a 5 hp long-shaft Suzuki, and it will push the boat about 3-5 knots, depending on current and wind.

I used Duane Dunn's info on his auxiliary mount as a baseline (although I believe he has a short-shaft). I believe you can find his install info either searching in the mods, or searching the forum, or maybe sending him a pm.

seems like there were a couple others that had info in the mod section as well?

Tahoe Jack documented the same aux kicker mod in the Modifications area ( not the forum) nice diagram with measurements, etc. I have an aux Nissan 4HP that pushes my at 4 kts on calm water, transom mount

It is a short shaft and the skeg touches water when mounted.
