The boat is bone dry everywhere. very baffling. only water (which is minimal) is under shafts. Water that is being pumped out is very clear but salt (so not fresh)

my emergency pump is coming one very 5 minutes. it is pumping salt water but can find no accumulation anywhere. I cant even locate where the pump is??

I have a 1994 440 EXpress with 3116 CATS. Very seriius sooting problems primarily on port engine. Have tried everything I can think of to solve and involved 4 different mechanics (Two CAT ones). Everyone is shaking their heads. Only thing that I have been able to do to minimize the soot is to...

I want to put an elbow on my exhaust to vent the exhaust out of the slip stream to avoid station wagon effect. anyone know ho far out of boat envelope I need to be? do you think 12 inches will do it?

I haver had three different CAT Mechanics from two different companies and they all agree. FYI. changing the pitch on the props was not advice from the CAT mechanics. The one company with two different mechanics was actually the CAT dealer.

Thank you for your comments and since 2018 I have followed the advice from Frank Webster. It made no change. The only thing that has helped is changing the pitch on the props but till gwetting sooting. Cat mechanic says (after two sets of injectors and 10 hours of troubleshooting that there is...

I have been dealing with this for 6 years. My port engine soots quite badly. I have tried all the obvious solutions- new injectors (twice), fuel sep, turbolators, setane booster and changing prop pitch. My props are n ow pitched at 7 which means my top speed is about 9 knts. I have 3 ideas, one...

I have a heat pump in my boat and has two zones, main salon and forward cabin. When connected to dock shore power, it works great but when using genset, only the main cabin will work. any ideas?

I put new props on that are 22x18. (they are not the stock one) these are the ones I want to repitch

Caterpillar 3116. I found out from Searay that stock size should be 22-22-1.75 Mine are pitched right now at 18 and getting redone to 16.5. (issue is both engines sooting badly, replaced injectors and other trouble shooting). props were 19 and changed to 18 and it improved so going to 16.5. I am...

I have a 1994 440 express bridge and have had a sooting problem. When I purchased the boat 7 years ago I was told props had been modified. I have since changed the pitch twice. I am going to change them again as still getting some soot. Anyone know what stock size props were supposed to be or...

My swim grid is very low to water and a fair bit of stuff grows on it. Is it ok to put antifouling paint on or is there a better treatment?

any idea where to find info on known hull vent issue?

I have got the drawings from Searay. Have explored the entire interior and no trapped water. Hate to say it, but core is next place to look. Boat is coming out for annual clean in march and will take a moisture meter to hull. many thanks

my boat has been listing and I have ruled everything out but a water logged core. 1995 440 express bridge with likely balsa. How does one fix?

After speaking with SeaRay, they assured me that there would be no danger in drilling an inspection hole into the chamber. I did that today,and with a inspection camera expected to find wet foam, or water. Instead I found a VERY dry chamber..... any thoughts on why boat lists to starboard? I...

I am very happy with the boat that I bought and have had no issues other than a list to starboard. My question was simple-is there an easy way to get the water out. I spoke with SeaRay today and they have suggested drilling a 1/2 inch hole to top of chamber. If no foam, then drill a 1 inch hole...

I was pointed out the list but was not worried.This was 6 years ago

I have a 1996 440 Express and she has listed to starboard since I have owned her (6 years). It has only been a minor annoyance but my winter project is to fix it. Today I discovered a bulkhead on the starboard side that is totally enclosed. It is about 10 feet long and would hold enough water...

I am planning to replace the pilot seat post for a longer one. There appears to be bolts that attach the old post to deck. If a bolt, are they attached to underside of deck? Ceiling in salon is other side. I do not want to remove fabric on salon roof. Does any one know if they are bolts or...
