I got a name of a new mechanic with many years of experience on Mercruisers engines. I will call him this week.

I am concerned to go at high RPM. That engine has about 1,000 hrs and the mechanic told me that it might blow up at WOT. So, before I decided to do anything, (rebuild it or sell the boat) I will take it easy. My intention is to get a newer 340 (2004+).

The engine runs fine but I don't want to go over 2,500 RPM

Thank you for your comments. The boat is, generally, in very good condition but the mechanic found the compression on the starboard engine to be 110 psi in several cylinders and 125psi in the others. The port engine has compression of 155 psi in all cylinders.

My mechanic, after checking the compression of my starboard engines told me that I need the engine rebuilt. So now I am not sure on what to do. Have it done or try to sell the boat "as is" as a "mechanic special" at a discount and telling potential buyers that one engine needs to be rebuilt. Did...

After trying everything, it looks like I need new risers. Thanks everyone for your input.

We checked the oil cooler also and it is fine. Where do you measure the PSI?

Well, the heat exchanger turned out to be very clean. Now what? The last thing could be the riser and the mechanic recommended to try to flush it with fresh water. Any advise still very much appreciated.

Thanks for your comments. Yes, they are fuel injected engines. Great to know that the temperature could go as high as 185. Manifolds and risers have been changed about three years ago. Does anybody know how high the temp must be to trigger the alarm?

I have a problem with my port engine (2000 7.4 fresh water cooled). Up to 2000 RPM the temp stays normal but going up to 3000 RPM the temps slowly goes up to about 180 F. I had the mechanic check the hoses and change the impeller. Also I had the diver check the sea water intake which turned out...

My old Carver 57 had it on the left side and so my old Bayliner 40. I like it better on the right side as on my Sea Ray.

Unfortunately, this type of accident is not uncommon. People sit on the bow, are thrown out and run over by the boat and propellers. This situation gets even worse when the driver is intoxicated, goes very fast and the people thrown out are not wearing a life jacket.

I cruised extensively on a Carver 57 including a trip from San Francisco to La Paz Mexico. The boat handled the ocean very well with no problems at all. See video:

I am glad to know that I am not the only one having stress when docking with strong crosswinds. Now I am looking forward of having a bow thruster installed and enjoy the day out without worry about going back to the marina.

Thank you for your comments. It is always windy when I come back to my marina in the afternoon with a narrow fairway and a sharp turn to enter my slip and I feel I would be more relaxed knowing that I have a way to control the bow if I have to. Besides this particular situation, I have no...

Has anyone ever installed one of those external bow thruster. I would be very interested to know if they would be any good in helping me dock against heavy winds when the used of the two engines is not enough. Thanks

Thank you all. I agree it's good and cheap insurance to change it.

Hello everyone. It has been one year since I changed the engine oil on my 2000 Sea Ray 340 and I only put about 25 hours since. In your opinion should I change it again? It still looks good. Thanks

I will check that. Thanks
