Go the 4108?

I recently replaced my Pathfinder(VW) with a Beta Marine and could not be happier. We went to the boat show">Miami Boat Show and talked to every one there. Stanley at Beta had me send the drawings with diminsions of the old Pathfinder motor mounts. He ordered the engine from England with special mounts to bolt right up with no additional charge, even got the boat show discount. Dropped right in, bolted down. I installed and lined shaft in half a day. I've got sixty five hours on it now, engine runs very smooth at low rpm's. Price was right in the middle.
If I ever replace another engine I will replace with Beta. Kabota parts can be found just about anywhere.

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.
