New Engine

[chris505]

Hi
Does anyone have experience or knowledge of replacing the Yanmar YSE8 engine currently fitted to our Hustler 25.5 with a larger say 12hp unit?

Thanks Chris

Is that the one with the horizontal cylinder? If so you might get away with a straight replacement of a GM10. Depends on the height above the bearers.

Cut my teeth racing a Hustler 25.5 many many years ago. Bright red one called Mooi Maiisie (or something like that). Lovely boat.

Hi Donald

Yes it is the horizontal cylinder, however the amount of space between the top of the engine & underside of cockpit floor is very limited.

Hi
Ours is also bright red called Miura She has just taken us to Holland for 4 weeks sailing, which went very well, but we do need a bit more power against a foul tide and no wind.

I managed to replace a YSM12 with a 2GM20F although space was very tight heightwise. I didn't have any problem with the width or depth, but was able to use existing bearers.

Talk to local Yanmar agent re replacement engine sizes.

Maybe other posters could recommend a suitable replacement engine from another manufacturer?

K6417?

Name may have changed but the sail number was K6417 (I have a faded picture of her on my desk)

My 25.5 has a 1GM10 which fits a treat with easy access for maintenance. The 2GM20 is only longer I believe and there would be plenty of space to accomodate.
Mine has the 2.62 gearbox ratio which needs a 13" prop but there isn't sufficient hull clearance for more than a 12". Check out the required gearbox ratio before you commit to any engine.
Nevertheless it pootles along quite happily at 6 knots with a clean bottom which is about the most you can expect.
