Re: Will tall aluminum center-bolt valve covers fit?
For one thing, I have never had any dealings with Ebasic or mich.motorz so won't even comment.
I also wouldn't put a rebuilt engine from any company in my boat. They spend little time and little effort to make it right. That is why they sell long blocks for 1500 bucks. They are junk.
Most rebuilders have a warranty on paper, that is never backed up.
If you want a new engine with a warranty you can take to the bank, then Merc or Volvo will sell you one. But it won't be for 1500 bucks. But they have dealers for parts and service when (notice I didn't say if) you need it. Try that with some of the cheap rebuilders............. ain't gonna happen.
Merc also sells some rebuilts......... and the warranty is good on them also.
I also know what I do when I rebuild an engine, and would have no problems running one of my engines after a total rebuild. But it's also not going to happen for little money.
If you are going to sell things cheap, you have to cut corners if you want to make a profit.
I have probably gone completely off course on your question, but automotive and marine are so different in what happens to the engine, that it's like completely different engines and thought processes to make them work.
