New boat-thoughts?

I purchased my first airboat. It is a 14 foot Laser with a 0-435-A Lycoming. I know this engine is old. However, it was rebuilt several years ago and only has about a dozen hours on it. It runs very well and doesn’t burn much oil. I’m hoping it will last me a little while. I’m taking my boat out on a few journeys and all seems to be working OK. I don’t know what kind of all the guy was burning. I’m getting ready to replace it with Arrow shell 100+. I am also going to aviation fuel.

I’m wondering about the motor. I haven’t been able to find a lot of information and there don’t seem to be many parts available. I’m hoping for the best and realize that I will be faced with some sort of upgrade in the future. What does everybody think? Any special things I need to consider?

Thanks. By the way, I am learning a lot from this forum.

I think you are on the right track
Keep good oil and fuel in it and enjoy it

If it only has a few hours on it it may have mineral break in oil in it

It might be a good idea to run mineral oil
For one more service interval to promote good top end seating in if is indeed a fresh re-build

Make sure you got a solid prop on it, not some old rotten POS that may let go and hurt you or the boat or someone else

Dont take no chances there

Good engines. A little under powered. Hard to find parts for. Rings are expensive. Use it and enjoy it while it is performing good. Consider upgrading to a more common engine later: (Lycoming 540 or continental 520). Some people bore the cases to accept 480 cylinders and this makes a great engine but I have noticed the 480 cylinders are getting scarce as well. Just my opinion.
