I am looking for an outboard engine to suit my Etap 21i yacht (My current outboard is a Honda 5hp 4stroke which has a manual start and I find it a little noisy, unrefined and underpowered for use on the Forth estuary) . I am looking for an engine with about 8hp that has an electric start, user friendly controls and is reliable. Does anyone have any suggestions. I am also looking for advive on 2 stroke and 4 stroke. Which is best and why?
Thanks.

This really is too much.

We've had threads on the subject of posting to all the YBW forums before, but you've really taken the biscuit.

If you want to get uptight about the advantages of two stroke over four stroke (or vice versa) and to canvass opinon for purchase of a bit of kit, kindly have the decency to at least just place a pointer to ONE forum.

There. Suitably chastised, and I've got it off my chest. I'll go and help myself to a wee dram before retiring.

BTW just sodding well buy a Honda 8hp. That's obviously what you want.

On behalf of the normal motor boating fraternity perhaps I can apologise for the attitude of some who do not think it appropriate on the motor boat forum to answer a question about motors in a civil manner, irrespective of who asks it.

Re your question. Two strokes are generally cheaper but have the hassle of adding oil,etc. They also tend to have a better power to weight ratio. Four strokes on the other hand are smoother, less inclined to foul up plugs etc on extended periods at slow speeds and more frugal on fuel. They are also generally more expensive and heavier than the two stroke equivalent.

One compromise is an oil injection two stroke engine. Suzuki used to do an 8hp but I am not sure if they still do. This gives two stroke power to weight but has its own two stroke oil tank and handles its own mix. Fuel tank therefore contains just petrol. It is still not as economical as the 4 stroke.

If it was me, I would go for a fourstroke.

Good luck

Well said Nick. I think that you'll find 4 strokes better suited for your needs as they should have better lower end torque, 2 strokes tend to be better for faster craft. Fuel economy will also be much better and they should also be quieter. Honda have a good reputation and I suggest that you look at them again along with Yamaha and Tohatsu.

I would like to thank everyone for their thoughts and ideas on the above subject. Very helpful with the exception of one response from RichB, who needs to get out more often and get a life!
