Longblocks would be fine especially if you run only 40 hours a year. You can also drop in a small diesel ( I have a buddy at Yanmar that told me that have a drop in replacement for just a bit more than a gas engine price)

I have no idea what the last poster is saying. I don't think he does either.

Re: Gas engines rebuild cost?
Not familiar with CC engine, dont know if they used the GM industrial block or not. Crusader used the GM Industrial block that has 4bolt main and some other more beefy stuff, little more hp @350.
I suspect yours are the automotive blocks with 2bolt mains and if so would go with long block.

Re: Gas engines rebuild cost?
I would not do anything until I ran a compression test. If that turns out OK. I would invest in new Edelbroch carbs, ( their great) electronic ignition, plugs, wires, larger flame arresters and let them fly. From what you say you don't run them hard. But with the new carbs, plugs, wires, ignitions and larger flame arresters your going to get a lot better fuel usage. Labor is the biggest cost to pull and rebuild. Your near Toledo call Motor rebuilders and see what they want to rebuild. They have done well with many of my friends. I also have an older friend in Point place that's all he does is rebuild marine engines. I would be more adpt to trust a local rebuild than an outside purchase should there be any problems.

Make sure the rebuilder knows how to do marine engine rebuilds. There are different rebuild kits ect.

Re: Gas engines rebuild cost?
1400 hours is entry level for these tough engines. We have 1400 on ours and they check out as new. I really am puzzled by your low oil preassure readings on BOTH engines. Those original AC gages are junk, but if they both read low, I suspect that your DC voltage is low. Those gages are actually re-labled volt meters. Do hook up a mechanical gage before you jump to any conclusions. Don't be afraid to run them at full throttle for a few minutes. You need to do that to make sure they are turning between 4100 and 4500 RPM. Try using 20W40 Shell Rotella oil also. They should not be ready for overhaul for another 1000 hours.

I fully agree with Maynard. Use mechanical gauges run compression check, if all is good run 'em for another 1,500 hours.
