New Engine Question

[Donjo]

Just acquired a 97 2100SR.

The block is cracked and the engine is seized. Wondering what are the replacement options for it? And what is a reliable source for new/rebuild Mercruiser engines? Very new to all of this....

My 96 2100SR that I bought a liitle over 2 years ago had a new First Mate rebuilt engine in it. The install of it was not great but the engine itself seems to run pretty good. Have had no issues for the time I have had it. There is also Jasper, Michigan Motorz and many others. I have heard good things about Michigan Motorz. Jasper used to be pretty good but I have heard they are not what they once were. No experience with recent stuff from them so not really sure.

I'd check to see whats cracked if anything.

It could be just a leaky manifold or head gasket the cause the hydro lock.

I'd pull the spark plugs and squirt WD-40 into the cylinders , and let then soak for a few days, then try to crank it over with a long breaker bar.

If you want to look at it more, pull the valve covers off, manifolds, or heads and look for rusty parts.

I don't think your going to make it any worst.... and you might get lucky.

I bought mine a few months ago with blown cylinder on the Port Engine. I replaced it with a Gen+ (Bravo) unit.

Other than a couple of issues with the carb not being set correctly, it's a great new engine for the money.

The crack is at the base of the block. Unfortunately the engine has been sitting for a few years like this. Would soaking it really do anything at this point?

If you are absolutely sure the block is cracked then it is done. Nothing you can do to save it.

Well sh*t.

LOL, sorry I couldn't resist. Honestly, there are too many to list. Do searches on REMANNED, Rebuilt, etc.

Check with Jasper Engines, very reputable and will stand behind their product. A national brand, I have one of thiers in my boat from the P.O.
