OK, Do you have a Prather Fun Cruiser? I ask because the stock prop size is 265. If a 275 won't dog the engine too much then I might try one & see what it does.

You can take a Homie above 13,500 rpm if you have one with a one piece forged crank , that has had the rod pin ground to .375 ,so you can use the newer ,heavier rods . Water cooling will make the engine last longer , and run better . A 167 carb , and a tuned pipe , on a stock engine will help , but if you up the compression , and know what to do to the ports you can run in the mid to upper 40's in a 48" hull , with a good setup . I have a few videos on you tube of engines I've built , all are when they are being tested after the mods . Youtube search "chipbreakr "

Thanks for the tips Jim, I have seen plenty of your work, very nice. I have a forged crank in mine at the moment but no boat, built it for a cracker but went with the Zen instead.
Here's a pic of the 50" hull me and my mate build.

RE: Homelite 30cc to convert.. Questions.
This is a helpful thread...thanks, guys.
I have a 30cc Homelite with clutch from a trimmer that I've had for years...runs fine but the trimmer has seen better days...time to put it to fun use I'll leave it air-cooled and basically stock to start out.
I've been designing and racing model sailboats for years, but this will be my first power boat. I've designed a 51" deep V hull that I plan to build from plywood, but I could use some help in understanding how to locate the engine and fuel tank for optimum balance. I know the design CG of my hull, but since these boats plane when they power up, I'm not sure how to compensate for that.
Can you help me?
Thanks...........Bill

RE: Homelite 30cc to convert.. Questions.
the reason your fun crusers are not getting the speed is they have subsurface drives, with a surface drive the prop is unloaded allowing you to run a bigger prop, the 167 carb, 275 prop, canister muffler is all great stuff for a homelite, they are great motors so dont get me wrong, but do keep in mind that for 200.00 a 260 zen is water cooled, more compact and will out run even a very well modded homelite. i do not want to take away from the homelites appeal but part of it is you can pick them up for free,and build very nice model boats with them, however after adding carbs, watercooling and pipes, you can easily have spent the 200.00 a zen cost, and not have near the motor, just food for thought,with the new motors coming out used zens should be a steal as well. hey bill most deep vees do very well at 29 percent cg. this is not a good tech answer and i will get blasted by rivit counters, but we make boats in lots of various lentgths and on most deep vees with a home light transom to spark plug at 12" works very good, then you can go from there, the homelight has good torque and will move a heavy boat just fine.its the lack of high rpms that keep there speeds down in that 37-38 mph range for most of us, there are some guys that have gotten more but these are good target speeds

Thanks for the help, Expresscraft....I will follow your recommendation regarding the engine location. I'm sure your comments about the relative cost of a Zenoh are true as well....but I'm not going to be racing, so my engine will stay aircooled and not have a tuned pipe or big carb. Even stock it'll be a lot faster than my sailboats
BTW...I checked out your nice website...the sport drive looks like it would be perfect for my project.

your homelite will be a lot of fun, i have not updated our site in a long time we do carry drives but the ones pictured are gone, not a bad thing what we have now our much better, hope to update the site soon, thanks, im not saying not to upgrade your homelite im just letting you have a measuring stick to help decide how much to put into it, as well as all the other people that will be reading your post,
