Loss of rpm's and grinding noises are never good. If it was knocking too...well, I'd start at the bottom end and work my way up. RPM loss is usually something starting to seize up, like a main or a rod bearing. Good Luck with it. Lots of help here for you!

The original motors were replaced with these motors in 1997. as far as i could tell with the numbers of the survey and buy looking at the carbs which have the 330 tag on them. As far as the drives the Kaama brochure says the trannys should handle at least 500 hp after that there was no warranty issued by twin disc. What happened is the the motor started losing rpm and started clattering really bad so i shut it down. The oil pressure was 30 and the temp was 170 when the noises started. it sill will turn over slowly and makes a bunch noise doing it. I am going to check the oil for water and pull a valve cover to see if i can determine anything there.
Jeremy, did you get into the engines yet? Wishing the best for ya man.

The Twin Disc trannies are pretty tough. I imagine I'm putting out near 500 horses a side, and the only trouble I had with them is when I blew a transmission cooling hose, lost all the oil, and burned the transmission up. The bad thing is, I had two new transmission cooler hoses that I hadn't installed yet.

Well some good new some bad
1. pulled the manifolds and valve covers spun the motor over and everything looks to be in order
2. the rockers and springs look ok none broken.
3. pulled the plugs all look good except for one.
Here is the bad the cylinder that we think is bad the plug is RUSTED SOLID in the head
The head bolts are also toast rusted. I am going to finish up pulling a couple things and get them ready to come out.

So was there waterin the oil? How about the oil filter? Did you cut it apart and was there metalic substance? Hopefully not catastrophic and just a good refresh will get you back in business. On the brighter side at least you found this before spring and are able to have things fixed for next season. You will also know exactly what you have when this is done. Good Luck man!
