Engine start is at 2:20 in this video. Clip of my 1984 Formula One boat just prior to winterizing. Ambient temp is 39F and engine is fairly cold, it is 9pm at night, so there is much condensation in the exhaust and PCV system. 17' (16.5' actually). Bought boat 8 years ago on eBay for $1000 with blown upper outdrive and cracked exhaust manifolds on a 4.3L V6 4 barrel. Fixed it, ran it great for 5 years, then self built and swapped a 1999 GM Vortec truck 350 with aftermarket roller camshaft, full stainless roller rockers, aluminum intake, 750cfm carb, aluminum exhaust mainfolds, electric fuel pump, Mallory distributor with advanced timing and twin pickup / amplifiers, air powered switchable exhaust routing, and a million gauges. Sold running 4.3L 4 barrel engine for $800. Runs great, almost touching 70mph very reliably. Total investment, about $3000 Easy transplant, 4.3L and 350 are same engine, less 2 cylinders, everything transfers over. 4.3L V6 is a great engine. 5.7L is even more of that greatness. Boat did 50-53 GPS with the tired factory 4 barrel 4.3L. Now cranks 68mph GPS with a 25 pitch Mercury Mirage SS prop and 1.5 outdrive ratio @ 5500rpm. Going for 70mph next year (leave the anchor at the dock, bump ignition timing up, run less fuel level, etc....). Boat originally did not have through-hull exhaust. Nees rub rail work and wo have bottom paint removed. Would also like to install a nice teak swim platoform in the rear, used to have 2 small fiberglass platforms which sucked, I removed them. Cheap fun, out-performs the big dogs, sounds decent.
