Light Weight Engine build

New to this post. I am looking to build a jet boat. I will be installing either a small or big block v8. Light weight is extremely important because it is going in a boat - allows for shallow use. I am posting on here to ask for advice on what the best application is? I am not after crazy performance (350 HP 400 ftlbs). Reliability is important. What is the best application from your experience?

Turbocharged aluminum 4 cylinder. You won't get much lighter than that. Even if you use an iron block its considerably lighter than a V8- cheaper too.

Or you could use an aluminum LS engine if you want to keep it NA. That power is easy to hit on one of those too.

You are kidding right?
SBC 350 with aluminium heads. Cant get much lighter than that and get 350 hp. I dont how much more a BB weighs, but unless you can get an all aluminium motor, the small blocks not even close

SBC Jet Boat

I personally have a 383 Small Block Chevy in jet boat. This motor has been in two different boats a 19 foot sleekcraft v-haul and a 21 foot eliminator tunnel haul. At first it was a mild build at maybe 400 HP and it was reliable and did about 60 mph. Now the motor is in a 21 foot eliminator with a 6-71 blower. Now I have no problem running with BBC jet boats. Power is only half the battle with jet boats. You need to have the pump built for your intended use and power output. If you build the motor yourself then all of your clearances will be alot different then a standard performance build. In a boat you want everything as simple as possable. Good luck with your project.
