So, GM won't release our dyno sheets, but they allowed Mercury to try to sell the LT-5 to others.

LT-5 came close to being a Bentley engine

That would have been a bummer.

Google Mercury 1350 & 1650 race engine's for (what made me think) newer LT5 based Twin Turbo marine engines.

There was an LT-5 powered boat @ an exotic car dealer in ohio last year. Unsure who made it or who purchased it....

Rick sure has the market cornered on rare LT-5 / mercury items!!!!

Three 1650s (two rights and a left, the middle one running a drive shaft) in a Fountain 39 should be just about right!
FU, do ya think we could lap Long Island in an hour and a half?
Stop for lunch at Montauk?

Miss Geico races the 1650 and will be in key west racing against the turbine boat of Qatar. They already raced in clearwater fl with the turbine boat winning with geico spinning out. Check out Super boat racing website.

Thanks Rob
