Happy New Year !
Boats still high and dry, small details to wrap engine (throttle-xmission cables, coolant recovery tank. Winters settled in, convinced myself a good idea to delay launch until March. Hull, rudder clean, prep and paint needs attention. I was was really looking forward to starting the engine for the first time! I stepped-up the exhaust hose diameter from 1 1/2" (M15, 11HP) to 2" (M25, 22 HP). The exhaust riser was build with a 2" output flange.
Concerned I may have mucked-up the exhaust "back-pressure"... ?
The hose run is approx. 15 feet, riser to transom.
picture after recent haul, 9/25. had been in water for 3 years.
