Hey guys im into this conversion scene, but from an alternate angle.

Mine is for marine applications. As you guys would know, rpm is everything when chasing speed in a boat.

I have an 18.4cc weedeater, bog stock for now.

The prop i want to spin is a 65mm 95,1mm pitch octura prop.

I was wondering whether you guys see any advantage in doin all these mods to a marine motor, where weight is LESS of an issue then in an aeroplane?

On another note, i will have an advantage, of a watercooled head so perhaps if i go ahead with a gas + glow setup i may have some cooling advantages, in chasing rpms.

On a side note though, am i better off ditchin the 18.4 and goin to a 25cc GMC 2stroke motor (looks like a ryobi or homey cant b sure?)

Its going to be heading into a 50" apache style deep vee hull (if that means anythin) with a surface drive prop (only partially submerged, makes engine rev out more easily)

THanks guyz,
Ben
