Hi all,
I have watched this thread develop with interest and would like to pitch in. I own a Macgregor with a 90HP fourstroke, the engine brand is unimportant because everyone has the best brand. IMHO, a 90 HP is absolutely perfect for this boat in terms of power, speed, economy and performance I have owned a few boats over the years and driven a few more in the Navy however I am no expert nor do I claim to be because every boat is different. I was always taught that a good rule of thumb for planing is one third of the hull out of the water and two thirds in when planing. This gives the safest, most comfortable and stable ride whilst at planing speed. I have watched the video and found that the blue boat is doing exactly that which confirms in my mind that the 90 is a perfect choice for the Macgregor 26. If a hull comes too far out of the water at speed, the balance is definitely tipped, and not in your favour.
Many people wrongly assume that speed means performance, this is a very dangerous assumption to make and history shows us that. One great example although very extreme that demonstrates this perfectly, is the Donald Campbell Bluebird incident which is easily viewable on Youtube

Before anyone attacks me, I know that this is a very rare occurrence and that it will not happen to everyone who goes fast or has a 140HP on the back. However, take a boat any boat, then put a very large fast motor on it and a few extra people aft then throttle at full speed. Once around 40 -50% of that hull leaves the water and you are going into a strong head wind or you get a sudden gust of wind in your face or even a bit of chop, then you are in the running for an Olympic gold medal for gymnastics.
To me a 90HP is the perfect balance for everything you want and need to do in this boat. I have not driven a Mac with a 50 HP engine, but I think judging from what some have posted, that it does have some limitations especially when fully loaded with gear and people. With the 90HP, I can get around 30MPH which is more than enough for any activity but in reality I rarely travel at that speed and it has more than enough pushing power at lower speeds. The video IMHO showed the blue boat doing a perfectly safe, smooth, balanced, stable and fast run and was probably costing quite a bit less to run than the 140HP. It was doing everything that a reasonable person could hope that this boat would do right up the limits of safety, comfort and true control ability. It did seem to naturally prevent the boat from getting into that state of possible unbalance. I certainly don't think engines larger that 90 are unsafe but I just question if you need to do anything more on this boat than a 90 HP would already allow, which is virtually anything.
I would also like to make it clear that I am not saying for one second, that the person driving the 140 was unsafe, he did an excellent job of proving that these boats are easily capable of safely operating with larger engines than the dealers, for whatever reasons, recommend. If I ever buy another Macgregor I personally would definitely stick with a 90HP because I am far happier with this boat/engine combination than I have been with any of my previous boats. I feel that it is only a matter of time until the recommended engine size for these boats will be a 90HP. When this happens and it will, there will be a lot of Macgregor owners with 50HP who will naturally be very unhappy at how much value will be wiped off their boats in resale value because the 50HP will then seem to be to a 90HP what a 30HP would now seem to a 50HP. I feel that this is part of the reason that it will not be introduced overnight but the writing is definitely on the wall. If people doubt this, just look how the dealers maximum recommended engine sizes has been creeping up over the last few years, 50HP then 60HP now 70HP. Also, please be aware that the change from 60HP to 70 HP maximum recommendation was quite rapid.
Another thing that really confused me was the weight issue. If weight is supposedly an issue, the Suzuki
70HP which is one of the engines recommended by Bluewater, weighs 156KG whilst a Honda
90HP fourstroke weighs 163KG, 7KG difference for 20 more horses??????????????. Bluewater are now making no secret that larger engines have better resale value which does nothing to help the resale value of those who have smaller engines. Look at Bluewater yachts website for proof of this then look at engine choices page of that site, it says it all.
http://www.bwyachts.com/Engine%20Choices.htm To be perfectly honest, It was this trait of rapid upward movement of engine size suitability and such articles that prompted my choice of HP, I got worried that a 50HP would be frowned upon by those in a market where a 70 HP was rapidly being seen as the norm and Bluewater publishing articles about better future resale values of boats with larger engines.
I must make it clear that I don't believe that either Macgregor nor their dealers are intentionally trying to devalue current boats with 50 HP engines or less. However, you do not have to have a degree in marketing to realize that significant devaluation of a boat with a smaller engine than the factory or dealers maximum recommended engine size will be a natural consequence. I am sure that they must also see this as a dilemma. I am not badmouthing small engines because it's horses for courses, but how many of you would honestly now buy a Macgregor with a 15HP knowing what you know now that the maximum recommended engine size is at least 50HP? When Macgregor say maximum recommended, we all know that it also becomes the minimum that must people will settle for. Read what Bluewater are saying about Macgregors with smaller engines compared to the maximum 70 HP that they recommend,
I certainly read it as saying that if you want real decent performance get at least the 70HP and they seem to be encouraging people to go for the 70HP. If I personally was looking for a new boat and engine, based on the article in the above link, I would now certainly steer away from anything less than a 70HP. I would think that because it's written by a Macgregor dealer so it must have some element of reliability. One must also realize that this dealer presumably also sells used Macs so they will have a good idea about resale values and what people now want. To those of you considering a new Macgregor, really do consider the pros or cons of a larger vs smaller engines and whether it will or will not offer a degree of making your investment more future proof. I am fully expecting to get slaughtered for this post but I mean no offence, it's just my observations and I believe that it is the natural order of things.
