Mainship with twin yanmars

Mainship 350 with twin yanmars. Are these decent engines?

Do mainship of that vintage have fuel tank corrosion issues? I donít want a twin engine boat that needs tanks redone.

Please any quick info would help. Not sure itís worth going to look at.

Most of the Yanmars are good engines, which model are you referring to. Aluminum tanks of that vintage generally should be in decent condition but it depends on how they were taken care of. Same with individual boats. Twins in that boat will be a bit tight for maintenance.

Thanks. These are the 230 hp. Not sure about turbos. Yes not really a fan of twin engine. Would rather have the single Cummins or possibly yanmar.

Inventory is so low - we have looked all summer and only found junk. Getting frustrated.

Yes, we sold our last boat and wanted something smaller and with gas engines since there are no marine diesel mechanics in our area. I wanted someone else maintaining the engines. We tried to buy a 34í Formula, failed survey. We tried to buy a 36í Formula, dealer sold it behind our backs. We finally ended up with a 41í Formula. Slightly larger than our previous boat and with diesels that are twice as large as the last boat. There wasnít another boat in the Great Lakes area that we had any interest in. Like you said short inventory. Well, good luck.

Yes, the Yanmars are decent engines. I've had 3 (but bigger) so far and bullet proof.
The only issue in that boat is the engine room is tight, so you'll have to squeeze around the engines to maintain them.
Economy is the same as the single, excepting engine maintenance which is small potatoes. And you'll love the maneuverability.

Although the extra engine maintenance isn't small potatoes in my book.

Yes, I’m probably not going twins. Just evaluating options.

Thanks all.
