Nice work,
boat looks good,

keep an eye on the bolts head, 2 bolts head can sometimes be their weak spot compared to a four bolts. specially now since since your 28cc has now doubled in RPM's.

Welcome to the forum and thanks for sharing the pics of this great build.

If I can make one observation - the header looks to be about 6" longer than most tend to run - this will tend to null any performance benifits from it - did you have a reason for this added length?

Looking forward to pics or clips of her in action

Good point from Matt,

what is the lenght from center of exhaust port to center of the 1" band?

This was a standard WTC header with 45mm cut from the end and welded in the centre of the bend in order to clear the flywheel cowl a compromise I know and I will not get the ultimate tune pipe length, the revs this engine is putting out I don't want to push it anymore.

I have made a copper cylinder gasket and loctite the bolts, in fact always loctite all the engine bolts and boat hardware.

I will not be able to run the boat yet because of a back problem, thanks for your comments and interest.

Hi Mick welcome to the forum mate,boats looking good im glad you decided to share your workmanship on here.As you know thats the same motor i ran in my old woody for a year or so,i can vouch for the quallity of the motor .Incidently ive been modding the new one i have here ,i opened up the ports as you suggested and it sounds a lot better than before.I also ditched the clutch too so that should speed things up also.I cant wait to change the carb and get it into one of my vees ,ill try it with a wtc pipe too but ill go for one of the ready made ones similar to Brod has on his lads boat.Mines staying air cooled,it will be interesting to see how she performs.Hope your back to full fittness soon so you can run your boat it should go very well.My woody was arround the 28- 30 mph mark with no mods in a wide hull so yours should be quite fast i reckon.

nice boat!
im interested in that radio box where did you get it from? as i hav a similar hull with wider than the normal 5" rails and am finding it hard to find a box that will fit.

shearwater111

I custom built the radio box from 1/8" Birch Plywood and covered with firbre glass tissue.

Great work! I have a boat that looks like yours (blade) and I have a weedy that I have been meaning to do something useful with.
Thanks for posting

Is it possable to use a actual weed eater engine to put in a boat? I have a un use un painted outrigger. It sives for a .80 to .90 nitro or a gas engine.

Outriggers are very weight sensitive - a weedeater motor would be fun in a Vee or maybe a cat - Riggers and hydros would do much better with a Zenoah, Sikk, or RCMK (or similar) dedicated marine motor.
