Bought an 03 320 Sundancer about a month ago. Immediately started having issues with the start up. At first the starboard was slow to Start and we had to use the emergency start once or twice to fire it up. Replaced all the batteries and now intermittently the port side engine will not click...

Has anybody converted a 2001 SR 340 SD from RWC to FWC, adding a Heat Exchange and converting whatever else is required? Boat has approx 470 hrs. Curious of the expense and will it be worth it? Boat was very clean...

So it looks like I possibly blew my Port engine as I was cruising along at approx 3400 revs the oil pressure dropped to 10 PSI. I grabbed the throttle and pulled it back in and shutdown in a hurry. I bumped the hatch up a bit while I was still moving and had wifey take a look and when I asked...

I just changed my risers, manifolds and spark plugs everything from the elbows down seemed fine. After starting the boat and taking it for a test drive I notice at very slow speeds near idle a knocking/studder noise coming from the engine. I didn’t have this problem prior to changing everything...

Hey guys, I know this may seem like a million times asked question, but Im not finding the exact answer to my question. How can I find out what model my 1984 boat is? HIN: SER94 T24 0684 20710 1533 84 What I know from there is that it is a Sea Ray from 1984. I can’t tell if it is a 207 model...

Hello All Tried using the search engine for this but no luck. I’m replacing both 7.4 L (310 HP?) gas engines on my 1996 370 SB. PO took the boat from lake to ocean years ago without heat exchangers so my cores are trash. Verified it. I’ll do a lot of the work myself but need long blocks plus a...

I’m wondering if anyone has ever replaced the engine in their 1997 420 Searay AC. I bought the boat last year and the engine (3116) blew in September from I believe captain error. We can’t figure out how to get it back in, if the floor needs to come out or the engine should go in in separate...

Heya, Soon to be newbie boat-owner here. I'm wondering if anyone has any good 'rule of thumb' suggestions for a maintenance schedule - (every X hours or Y months do Z). What I have so far (for a boat slipped in salt-water): - Every 15 months to a few years haul-out and do a bottom paint. -...

I have gotten into an argument with my local workshop regarding work hours, so I would really appreciate if there´s anyone that can give me an honest estimation under the following starting conditions: - Boat´s on dry land in the shop - Sterndrive is off - Enging hatch is off and out of the way...

Hello fellow boaters, I have a 2005 Sundancer 280 with twin 4.7 Mercury Engines. I just encountered a very unusual problem and needed some help. My boat used to take off and plane within 30 seconds at around 3500 rpm, however, as of about a month ago this has stopped. When I floor the boat, it...

Hello, I said a bit more in my intro, but hoping to get a jump start on fixing a few bugs that have popped up in getting my '89 Bowrider 200 (Merc 3.0L) back to reliably running. Picked it up from a good buddy who's dad had passed on a few years ago, he wanted it to go to a friend. It had been...

Hi there. my son returned my beautiful boat damaged. Trying to find a 5 or 5.7 engine. back seat replacement, and travel top replacement. Would consider a new all around topper too if in good shape. kkeatingek@gmail.com thank you

I have rust at the manifold gasket, motors mounts and other part on and in the engine cabin. Any thoughts on the pics? 79 hours on the engine. Mercruiser 4.3MPI 250hp.

I'm a noobie to boating FYI. Just purchased a used Sundancer 300 and drove it to Port Washington, NY from Patchogue, NY with no incident. Took it out a few days later with no incident. Docked the boat, plugged into shore power and left the boat on shore power overnight. Came back next morning...

Just bought a 1978 240 SDB and I am looking for a shop manual, but am having no luck. Can anyone help? The boat needs a bit of restoration and I thought it would be a good idea to know where everything is supposed to go and how everything is supposed to work. Thanks

Just bought this SRV 240 last week. Trying to get some new parts for it but I'm having a tough time identifying the exact make and model of the engine and drive to get the right parts. Here are some pics:

My Mercruiser MPI 50 engine turns over, but will not start. We have replaced the rotor cap and crank sensor and checked the coil. There is fuel pressure. It appears that it is only generating a yellow spark and not a nice blue spark. Any thoughts or ideas. My mechanic and I are out of...

Hello, I had to change the relieve valve on my hot water tank, I decided to use the occasion to run the pipes to the engine room so I get hot water from the engine. I got the pipes in the engine room, now where do I hook to the engine? Caterpillar 3126 350HP Marine engine. Link to a video or...
