Offshore mounts are more adjustable so it may take a new bracket set, but should not be a big deal.

Shouldn't any Merc high perf. motor slap right in with minimum effort? 496, 500 (efi/carbed), 525efi, 525SC, 502, etc. etc. etc. Not really that big of deal no?

Wouldn't the cheapest route be to buy some new blocks and throw 'em back together?

I have 2 454 long blocks for sale if you are interested one has 25 hrs and the other has about 250 but the blocks and heads are good. They were running when I took them out to repower a customers boat. And by the way you can put any big block chevy in your boat will only a little extra effort gen 4 5 or 6 it dosent matter. If you have any questions call me @ 714 369 7410 and good luck.

I have found that as you shift from generation to generation what you run into is accessories not bolting on and having to hunt for brackets and stuff. The easiest thing is to go with the same long block generation you have so it all bolts back up. Getting new blocks is an option but by the time you pay a machine shop to assemble it with all new rings, bearings, and miscellaneous stuff you can by a reman from a large scale builder and be back on the water in days instead of weeks or months-assuming you are just going back to stock power.

Anyone know of a quality shop out in Havasu to help grimmy out? I think he needs a second opinion from a shop that can give him a qualified estimate for insurance.

I am repowering a 35 Formula with 2 new GM 454/425 Gen 6's. There is very little different on the 454 Gen 6. I had to drill out some brackets from 3/8 to 7/16 because the Gen 6 head bosses are all 7/16. We also had to rebalance the Gen 4 flywheel, but it does work. Little else has to be modified. The engine mounts and bellhousing bolt right up.

Hope this helps.
