Te Hyperformance Products, www.hyperprod.com . Finding a 4-bolt water-cooled head might be tricky as the others use 6-bolt heads.

Just a guess, but isn't the RB made by NovaRossi? Maybe one of the Nova marine heads will work for you...(they're 4 bolt)

True, Rossi and Nova Rossi are two different companies and owned by brothers. It's a big family mess there. Nova Rossi does have 4-bolt water-cooled heads. I've seen them in 2 colors but the combustion chambers are different for each.

Merry Christmas!
Interesting hull - I like the colors too. Cool looking deck; looks like a Youngblood. What's the hull bottom look like?

BTW; here's the Rico 20 I'm finishing up. I just need to complete the radio installation, and it should be ready to try out...



I'll be running an inboard converted MAC OB in it (much like a CMB LS with a different port configuration).

Very nice looking hull, and I like the hardware too...! What make of hardware is that? BTW- how did that water cooled head conversion work out?

the hull and running gear is all x-cell products equipment. the head we turned down the original air cooled head into a head button, and used a water cooled top off a ops motor. with a litle file of the bolt holes they all lined up! should be finnished in the next week. waiting on a few more parts!.
