aeromarine xxx outer limits help.

[wingnut]

I'm putting one together for a friend, it's been quite a while since I've built a boat. Is there a measurement for spark plug to transom so i can get this motor where it needs to be? any help would be greatly appreciated

That depends a lot on what else you put in there, put on everything and make it balance at aprox 31-32% from rear end.

definitly what joern said, put all the transom hardware on with the cable and prop, put all the servos in the radio box including the battery. when this is done then you can position the motor with the pipe attached to the motor. calculate 32% of i think that hull is 45 or 48 inches. been a while since i saw a aeromarine

Thanks guys. What about fuel weight?

What works for me, I position my fuel tank where I'm going to want it, & fill the tank half way.

idealy if the fuel bag is at the center of your c/g that would be perfect but yout c/g would wind up under the pull start most likely. i have one of those adjustable iv bag mounts that let me move the bag fore and aft but it will most likely go as close to the pull start as possible

 

[wingnut]

when mounting the stinger should the bottom of it be even with the bottom of the boat? what's the usual height for these?

 

[john v]

i run about an 1/8'' above the bottom and this works for me
