Some of the older merc magnums had them. They used to be more common in small blocks but


truth is that any small block with less than 400hp doesn't need 4 bolt mains. And my own


truck gas engine experience has been that you'll see 50 thrown rods and broken pistons for


every broken crank or main cap.




I agree with the rest of the post though. You're better off with the 350 than the 305.

I have never seen a 4 bolt main yet in common marine engine, OMC, Mrec, Volvo?

In a *quality* marine engine, they use a steel crank, 4-bolt


main caps, and forged pistons. This is not to say that you


will find these desirable items in every marine/auto engine.


The head gaskets are more corrosion resistant also.




None of the differences are critical, if you don't use the


engine hard, or run in salt water. If you do either, then


you want the sturdier components.




350 to 305? Didn't you notice you're going the wrong


direction? No, you won't notice any improvement in fuel


economy. I'll give you one guess what you *will* notice,


tho.




FWIW, the "targetmaster" is the el cheapo GM replacement. I


wouldn't buy one.

Agreed. I have a 305 in my '77 Marquis. It's turning into a nice boat, that is, when i get the interior finished. But if I have problems with the stock 305, I'll put a 350 in it's place. A lot better power per fuel usage.








Just curious Tim ... where are you reading these posts? You just

replied to a post that was made on August 14, 1999.


Well Rich, this is a boating group isn't it? I Especially this year, when I'm gonna start working on finishing my boat and planning trips I'm doing a lot of research. And I find old threads that have some good advice. People who never post in here do the same. That's how I got onto rec.boats many years ago, by doing a google search on a boating question. So, that's what I do.

BTW- I made up my mind that I won't be evolved with political/religious threads any more.


That's an absolutely SPECTACULAR idea!

I think you should also consider finishing and planning trips on those two Moto Guzzis of yours!
And, if you want to talk about them, that would be great also!

The big question is whether I should hang the Winchester

or get one of these to hang in the trailer.
