Looking on their site, a new 350 FWC MPI engine is just under 10k on their website. We also put two new Marine Power engines in our 30' Luhrs 3 years ago, and we have had 450 trouble free hours so far.

If MP is in the mix you should take a hard look at the Direct Injection 5.3 or the 6.0.
5.3 is a Gen 5 small block, alum block and heads. Very light (~150-200# less than a 350) and extremely fuel efficient. GM is using them in the 1500 series trucks. 355HP and a great rep but just now used in marine applications.
6.0 is a Gen 4 small block (LS series); Iron block and aluminum heads. ~100# less than a 350 and much more efficient. GM uses them in the 2500 series trucks. PCM also sells them and they have a reputation for being almost bulletproof in both boats and trucks.
Both are FWC and have variable valve timing. Both have aluminum pans. The cylinder deactivation BS is NOT used on the marine versions of either one (thats good).
