Also I dont have any hoses and fan it sucks water out of the lake.....

I am going to keep this one relativly stock but here in the northwest they are also thinking about changing some of the vintage class rules so Im just keeping my options open

I have an old 60 y class hydro (smallest class)
that has a a12 I have to keep the engine relativly stock but I was looking for some ideas on upgrades. (what carb to run,ignition,ect..) I was also thinking of pulling off the flywheel and running a flexplate from an automatic since im only using it to start the engine. Also has anyone run nitrous on there engine? If so what did you do to the carb and such? If anyone has any good ideas please feel free to give me your opinions..Thanks Dan

Now that I have everybodys attention . I am new to this site. My problem is I picked up a little 130 class hydroplane and its running a datsun engine. I have no idea what it is the only numbers i can find on the engine are

engine# 12 408840 and another 21118345
carb# dch306-105/4201h

If any one can help me out it would be great I need to get this thing in the water before labor day.. Thanks Dan Also can I get parts (aluminum flywheel, better carb ect..) Thanks again.
