Maybe give these guys a call, I've gotten kohler parts from them before. Here's a link for a kohler 6.5 carb kit but you need to know your spec...
kohler may have a rebuild kit. I believe the carburetor is Mikuni. I had a kohler 7.3 and it was a Mikuni. If you know the make and model of...
Carburetor jets most likely have gunk in them. Get a rebuild kit for the carburetor and rebuild it. Clean the jets out real good with carb...
What choice would he have assuming all is right with the engines? timjet's post is a bit confusing in that on post #12 he first states it...
Thanks for the response. My motors are 370HP rating and the top is closer to 21 knots. My cruise is 17 knots. You have a bit smaller motors...
Hi, Anyone have an 01-06 444 here with TAMD63P 370 volvos (2800 rpm motors)? I'm trying to compare cruise speed/rpm. I'm propped at 40rpm over...
One place to check is the regulator where you connect the city water. Mine was leaking there on the inside where the fresh water hose connects.
I have a Raymarine Cam100 camera wired to a E120W display on the bridge. To be honest I never really use it. The picture isn't as good as I...
Did you end up putting the pyro and boost gauges on? Just curious how you made out with that...
Good Luck!
In theory the prop on each motor should affect that motor only but it does need to be pretty balanced across both motors. You EGT and Boost gauges...
Sounds that way, I agree but as far off as he is on making WOT rpm under load he'd have to take out many inches of pitch out of the prop - that...
Tim, good luck and keep us posted! It's on'y a machine, at some point the answer will show up. Hugo
I would think that when you have RPM decay you would see it on Vacuum or Fuel pressure gauge if it's fuel. I'd focus on boost and pyro next to...
I feel your frustration. Also install a boost gauge so you can see what pressure the turbos are putting out. What does the exhaust side of the...
If re-pitching didn't change rpm, problem lies in motors...
Did you follow Tony's article? http://www.sbmar.com/Maintenance/PDF/Low-Power-Troubleshooting.pdf Do you have Boost and EGT gauges? Without...
Are you sure your linkage is allowing you to make full throttle? I have mechanical linkage, is yours mechanical or electronic? I have heard of...
Cap, Thinking more about your poor handling problem if you were cruising at 12 - 13 knots like you said was normal I could see it handling poor...
I pretty much run with the tabs all the way down - factory tabs. If I let up I see a decrease in speed. On a head on 20 - 25 knot wind in 2 - 3'...
