8 hp or 9.9hp in at CD25 well

[abutkus03]

I've read some posts that suggest its possible to put and electric start 8 hp or 9.9hp motor in the sell of a CD 25. Do these size motors really fit in the well. I've measured mine and it doesn't seem that big. Pics would help.

You don't want to do that.
Why?
Because the weight of these bigger motors will make your CD 25 squat
to the rear, and a squatting sailboat is SLOW!

There are a bunch of threads here about this. I realize to get an electric start you have to go to an 8hp but it will make the boat squat. Make sure no matter the hp you fill the front water tank to help level the water line.

If you go for an older 2-stroke Johnson/Evinrude the 6hp and 8hp are the same weight. The difference is in the intake/carb design not the engine itself.

Mercury makes a 9.9HP electric start 2-stroke that weighs about 60lbs today. Unfortunately it's not available in the US. The US 4-stroke models are about 95lbs.

Well, you can put any kind of engine you want in your boat. But you don’t need to. I use a 9.9 hp Honda high thrust four stroke to push my 18,000lb fully loaded CD 36 Far Reach. I can make 5.9 knots on flat water and cruise at about 5 knots at 3/4 throttle or 4.5 knots at 1/2 throttle.

A four stroke is a heavy engine. I have a 9.8 2 stroke tohatsu we use on a small skiff. It weighs about 60 lbs. My 9.9 hp Honda four stroke weight about 114 lbs.

A 6hp sail pro is plenty of engine and much lighter which will help keep your boat on its lines...which means it will sail better than if it’s squatting in the stern. It will also be easier to lift out of the well and while you may not think that important now I suspect you will when you are trying to lift in or out of the well.

People have all kinds of reasons for why they want a big engine on their sailboat. But none of the reasons are because it will making them a better sailor or help them better enjoy “sailing.”

A 6hp with the proper prop is all you need. A well maintained outboard will start on the first or second pull of the cord. Electric start is just more weight, complication and expense. And is you really want your CD25 to sail well, you'll pull the outboard out of the well as soon as you can.

I concur. I specifically wanted a pull start on my outboard...one less thing to go wrong. I have not regretted it one bit. I wanted the high thrust Yamaha but they only offered the 25” shaft with electric start. The Honda, with the pull start, has worked perfectly. I have heard nothing but good things about the Tohatsu Sail-Pro.

Thanks everyone for your advice. I'll share it with my wife, who wants and electric start motor.

Does anyone have experience running a two-stroke outboard in a motor well? How much smokier is it than a four-stroke?

The reason that I ask is that I am considering replacing my 2016 6HP Sail Pro with an older two-stroke. I would do this because it would be lighter and smoother. But, I have been forewarned that the fumes will be excessive, and that I am better off staying with the Tohatsu, which I simply do not like.

Comments on other possible four-stroke motors that I could install would also be appreciated. The motor well is tight, so I can't imagine that all modern motors would fit.

Thanks.

My Ty Senior (22' hull) has a motor well that's probably similar to yours, I have a Yamaha F4 (4hp 4-stroke). It seems to have enough power (I can do 4-5 knots all day long if necessary), starts on the first or second pull (I maintain it myself pretty thoroughly), and is reasonably quiet and clean. Weighs about 45 pounds. It's extremely miserly with fuel--the F4 is actually in the Guiness Book of World Records for going over 67 miles on gallon of fuel. I normally buy 5g in May when I launch and have leftover fuel when I haul in October.

Chris, What is it that you dislike about your Tohatsu?
Just curious, I had one on my last CD25 and loved it...

[casampson]

It's noisy. It is rough at idle. It sometimes revs inexplicably, and it can be difficult to start when warm.

I ran a can of SeaFoam through it yesterday. I hope that helps.

I do have an Evinrude 6 hp two-stroke on a skiff that I love. Smooth and powerful and actually quieter than the Tohatsu. I was thinking it would be a good motor to put on my CD 25 if I could find a good one with a long shaft. But I am concerned about the fumes that would be bottled up in the well.

My Typhoon Senior came with a 2012 9.9 HP Yamaha 4-stroke outboard with electric start and it fits in the lazarette well just fine. Seems a bit of an overkill though and I'm thinking about selling it and getting a manual start 6HP 4-stroke. It's been yard maintained since new. If anyone in the Southern New England area is interested in it, please send me a PM (not an email - I don't seem to get those)).
