whats needed to put a car engine

[CAMERONWILSON]

i have a buggy that i dont wont anymore,i have a dynaite mach .26 in it that is smoking fast runs about 65mph and i was thinking about putting it in my boat that im building,what all needs to be done to do this.

it has a huge head on it so iwouldnt think that would be an issue as far as water cooling but what all else would i need to do.???????? any suggestions would be helpfull,thanks

A lot of .18's car/buggy engines are being used. Cheap horspower.

The long pilot(clutch) shaft has to be cut and the output shaft fitted with belt grooved flywheel with a 3/16" (.187") flex collet and the aircooled head usually does the job.

If it is exposed in a rigger with alot of airflow you might even need to machine off a fin or two.

I run RB engines in my riggers and OS in My mono's All I had to do was get a carb, build a cooling head (optoinal) and make a flywheel. The run fantastic and are not slouches by any means they keep up to the fastest in our club.

I've had a lot of experience both good and bad in converting car and truck motors over to boat use. Some work great and others well...... don't. SG shafted engines and those with slider carbs are a little trickier.

You can remove a lot of the heat sinks if they are exposed to the air. You may only need 3 fins on the head as the cooler air plus the water keeps the temps sometimes too low. They're made more for use on a hot dusty track under a Lexan body so they do have a lot of fins.

Two problems can arise with SG shafted engines, getting a flex cable collet that will thread on and next is having enough threads to be able to get a flywheel on.

Some of the car and truck engines have a lot of RPM but not that much torque so you might have to really drop down on the props to get any kind of speed out of the boat. That's what I ran into when trying some more high-performance engines. The low-dollar engines seemed to work better as their timing must be better for our use.
