yanmar vs yanmar?

what is the difference between the yanmar marine diesels for powerboats and the engines for sailboats? the major differene i see is that the power engines have more hp then the sailboat engines. can you put a sailboat engine in a small powerboat that only needs a 30hp diesel? are sailboat engines from yanmar made to run as long as the powerboat engines?

sailboat engines
Yanmar - Sailboat engines

powerboat engines
Yanmar - All can enjoy confidence in their YANMAR power. They have chosen the toughest and most durable power packs available for pleasure boating.

thanks
John

engine displacement, number of cylinders, horsepower and torque

you can use any engine that is the correct size for your application.

Re: yanmar vs yanmar?

There are lots of Yanmar "sailboat engines" installed in power boats. There is nothing specific to sail or power in an engine. If you need 30 hp engine for your powerboat, then buy a 30 hp Yanmar.

FWIW the small, normally asipirated Yanmar diesels last a lot longer, often 10,000 hours or more without major work, than the high horsepower, turbocharged, seawater aftercooled "power boat" engines.

Re: yanmar vs yanmar?

i am just running numbers and practicing and just messing around with numbers boats water line GPH and all that good stuff.

so pretty much the only reason they are labeled "sailboat" engines is because they are not 150hp+ turboed and all the good stuff that a lot of power boaters use?
