Hi, We own a 97' 355 AC with twin Crusader 454 Xli's. My question regards the synchronizer gauge at the helm. Where does the input to drive the gauge come from? The Gauge is always pointing in one direction or the other, regardless of engine speed. Does the signal come from the tachs or elsewhere? Any help would be appreciated, I believe the tach's to be accurate based on what I hear from the engines. Or does the signal come from the engines? This is just more annoying than anything else.

Has anyone experienced a loud clunking in the prop shaft at low RPM. When adding just a little power it goes away and runs great. We greased the zerk fittings and that helped a little bit but it came back.

The boat is a Carver 36 gas engines.

My husband probably thinks im on my 4th mid-life crisis at the ripe age of 34, but im really just searching for his next tinker project. He is an aeronautical engineer and from my boating childhood, I knew this purchase is the gift that keeps on giving, aka money pit. We will never run out of things to work on with this project.



If anyone out there has experience with this ...

Hello all,
Not sure if my refrigerator is working up to par as it hasn't froze the water bottle after 24 hours.
Of course it has been in the mid 90s and hotter the last week so thats not helping.
But in case I need to purchase a new frig, what size did the 2001 350 Mariner come with?
Cant find that info anywhere.
Thanks

1998 400 CMY, has (2) 454 7.4l mercury gas engines. Access is very difficult to the last (2) batteries. What are the PRO's & CON's of switching to Lithium batteries? Assuming it can even be done.

All (3) current batteries need/want to be replaced.

Thanks in advance,

We have a 1989 3807 Aft Cabin. The aft cabin has a window at the back. It is sealed. Just curious if this has been replaced or was it original? A friend has a 1990 35 ft with an aft window that opens. Thinking this would be our “escape” in case of fire, etc. any thoughts?

As many of you have known, I have had some recent issues with my 6.5 Honda powered Kohler genset. I believe it to be a 6.5CZ (per the build sheet) The ID plate is missing, so it is like looking for a needle in a haystack. I have pretty much seem to have it running and not shutting off. However, need one help on the following:

The coolant will expand into the recovery tank, but not siphon back in. Tube is connected to the bottom of recovery tank and no leaks. ((Pressure cap was new with heat excha ...

Hello! New owner here. I just bought my first Carver. A 1990 Mariner 3297. She needs some work, but the technical threads I've read on this forum seem very well informed and the users seem very happy to help. I'm hoping to get my boat working properly and continue to be an active member here for a long time.

I cleaned and oiled the airsep filters but I think I applied too much oil. Had a fair amount of excess which has drained onto oil pads.

I am concerned about damage to the turbochargers.

Thoughts and opinions welcome.
