That's a fairly popular engine to convert, if you do a search in the engine conversion forum (if you replace the forum ID # in the address of the airboats page with 92 it'll take you there) you'll find numerous posts. If I remember right the coil on that engine mounts on the saw housing not the cylinder so electric ignition would be easiest.

You say your boat is under powered what size & how heavy is your boat?
The output shaft on a chainsaw engine needs a left hand thread for the prop adp. witch is good you can use a Tractor prop instead of a pusher prop.


These boats have a 41cc Robin engine on them . they are not chainsaw engines

its now running a homelite 30cc with 14x6 prop it weighs 27 pounds and is 25x39, it is one of ptr34s hulls that he makes, i think it simpley needs more power, is the 42 even enough power or what would be my best bet for this a cy engine? i plan on lighting the cage some but its pretty simple not much to take of but if i get a diff engine i will need to almost rebuild the thing any how, thank you for any help

Bushwacker, have you played around with your prop ? I'd have thought 16 to 17 inch prop on a 30 Homie ? if you are running a 14, you can go up a bit in pitch ? Is the engine over reving with the 14 ?

What size props are other guys running a 30 Homie on?

people usually run a 16x8 to 18x8 on those engines, a 14x6 wouldn't get you as much thrust...

I use a apc 16x8 prop on that size of motor myself
if you are low on power check the compression of the motor it may need
re ringed or replaced . a 14/7-3 blade may still be to small , it was for me
good luck
