    Best way to gain a little speed with 40hp engine

    the prop on there is probably best. does it allow the motor to go to WOT RPM? only way to get any 2-log pontoon moving faster is to add a 3rd log, add lifting strakes to all the logs, and add a lot more hp. BTW, your pontoon boat will move between 16-18hp with anywhere between a 25-60hp...

    Mercruiser 305. Water in cylinder.

    I'm leaning towards bad riser gasket or too much weight in the boat. (Could be cargo, could be water soaked flotation foam) Measure the SWL to riser dimension. Should be 14"+ Do the leak down test. May want to pull the elbows and inspect the flappers

    Tachometer for 1978 Mercury 500 Thunderbolt

    Tiny tachs are ok. However any outboard 2 stroke tach will work What speed does your boat plane at? If you hover around that speed, you will burn more fuel than you would at WOT

    Tachometer for 1978 Mercury 500 Thunderbolt

    You should be burning about 25 # of fuel per hour with a 50hp 2-stroke You will burn more getting up on plane

    Boat Load and HP Rating

    More than 3hp will fold your raft In my teens/twenties I had an intex inflatable rated for 3.5 people and 3.5hp. a 3hp Eska and just me, giving it any throttle folded the boat and would almost swamp it. Even if I over-inflated it Abandoned the outboard, used a trolling motor and a group 24...

    Mercruiser 120 Fuel Help

    Dwell is not .022. that is the rough gap. Dwell is 34 degrees If dwell is off, coil saturation time is off and timing is off. I would tighten your rough gap to .018-0.020 and it will run a bit better. You probably did not file the points, so your rough gap is already different than what...
