oh man if you never used urethane 2k primer you are in for a very pleasant eye opener.

You're no fun that's how we all learn. I dont claim to know what Im talking about with authority Im theorizing.

Small hat mafia, when you understand that, when you question everything you are being told about history, start reading between the lines, the forbidden "conspiracy theorist" word, only then do things start really making sense. There is a reason the world has gone bananas because people stopped...

Nooo you're supposed to tell me how it's wrong. Dang.

I got so many memes this forum isn't ready for its unreal.

ok Im going to bite on this too. stock engines have the most base compression over a mod engine so need the least help scavenging as the pressure through the transfers is significantly higher.

so I'll bite....what the frig is "pipe ringing"? to answer the OP updated post ....it doesnt matter its a stock engine just go with what fits.

I use klotz too. I watched several records set with boats running super techniplate.

the reason the piston is carboned is likely because he was likely running Motul 800 which has double the flash point temp over redline. The engine was never getting hot enough to burn off the oil. He could have also ran too much oil given that it has so much more heat tolerance.

what exactly are these oil brands made of that makes them different? instead of talking our favorite brands lets dig into the actual chemical and molecular differences. also how is everyone running through 5 gallons of gas? I burned 2 gallons in 2024 between 4 boats. It takes me about 150 laps...
