Hard to go wrong with a perkins
, but as was said, will the installation
work out easy? The Yanmar
mechanics will tell you to run the engine at near max rpm
. The only way they get their HP rating is at high rpm
. Really just a smaller engine tuned to run at high rpm. I just dislike sounding like an airplane when I'm motoring! The Perkins
have replaceable cylinder sleeves, so if rebuilt right should last forever. I cracked a piston in my Yanmar
30 hp with a little over 2000 hours on it. The other engine had to be replaced under warranty with less than 500 hours (catamaran), although popular and a good rep, they are not bulletproof.
