    Manual fuel pump restrictions?

    NO a similar mechanical pump in a 1972 impalla wagon had to pull the fuel 22 feet from the tank thru smaller ID fuel line, as well as pull the fuel vertical up about 1-1/4 feet. the mechanical pump in good condition will suck in the walls of the tank a bit prior to starving the motor for fuel...

    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...

    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
