New Maxum Owner!
2 months ago I had the opportunity to purchase a 1997 1900 SR with 4.3 at a great price. The only CATCH was that the PO believed the boat to have suffered a blown head gasket while underway 2 years ago... It hadn't run since.
So taking a risk, I purchased the boat and brought her home, excited about the prospect of cracking the engine open, replacing the head gasket and putting her in the water for years of family fun. After removing the heads and intake manifold, I saw the crack in the block. And rust. Everywhere.
I will not be deterred. Purchased a running 4.3 from a 1998 Chev S-10 Blazer with Vortec heads. Found a pair of rebuilt Vortec heads. Removed the old motor from the boat and set about rebuilding the donor motor. The only parts I reused from the old merc motor were the camshaft, for which I built an electrolytic rust remover and hand polished the lobes (saved me some serious bucks) and the intake/carb.
New motor went back in 2 weeks ago, I tidied up and replaced some wiring to get the starter cranking strong. She runs like a top! Now just waiting for a nice Seattle day to slide her into the water!!!
I'm thrilled to be part of the community and hope to give as much as I receive.
