So I finally own a new enough boat to have some of the modern electronic gauges. I have done multiple web searches and have gained just enough knowledge to be dangerous, but I have a few questions..... 2005 260DA with the system tachometer and speedometer gauges. My understanding is my engine...

new to me boat has sprung a leak (2005 SR 260DA with 350 MAG MPI, B3). After close review I am able to determine where it is coming from, however I'm not sure how to go about repairing it. I forgot to take a pic and the boat is now 150 miles away again, so pls bear with me+ I am just now...

sold my last boat that had a tower with radar. Because my tower could fold down, I didn't realize that any newer sea rays that I was interested in (280's, 290's and 300's) all have permanent arches. I also came to realize that none of those with arches would fit in either of my storage units...

'88 Sundancer 270. Since I've owned the boat (4 years now) the fresh water system system on the boat hasn't worked properly. Hasn't really bothered me too much since we don't overnight on it a lot. My head has a freshwater pickup through a seacock so that is fully functional. I have both a...

Came off my prop tonight, noticed a hairline crack, pulled it right off. Can I run the boat without it?

alpha 1, fresh water cooling system, uptake in the lower drive I splashed this past Sunday. Two things I noticed: 1) my port motor would overheat when idling at a low rpm. If I was moving or revved the rpm's up to like 1100+ the temp would drop right back down. My guess this is an impeller...

OK, just replaced the alternator on starboard motor for irregular voltage spikes. Now it appears I have a starter going out on my port motor, but wanted to describe the situation to verify before I go replacing it because like everything else in these old motors, it sure isn't easy to work on...

1988 SeaRay 270 Sundancer, twin 4.3L motors, original, approx 1400+ hours on each. Many hours trolling. Boat is mechanically and cosmetically in great condition for a 30yr old classic. Last season I noticed my starboard motor had developed an irratic rpm drop while trolling. I had also...

not sure if my set up is stock or not, but here is what I currently have. On top of my gas tank, I have two gas lines that exit the tank that go to each motor to supply fuel to each motor. Attached to the tank I have (2) Fram C1110PL cartridge fuel filters. From there my lines run to the...

started mid-season last year, I think these are unrelated, but both on my starboard motor. ISSUE #1- motor idles and runs smooth, EXCEPT every so often it "surges" to a little higher rpm. Notice this when trolling (fishing) and when under way on plan. It's enough that it causes the motors to...

I believe my thermostat may be stuck open on my port motor (GM 4.3L 175). The reason I suspect is it recently takes a lot longer to warm up to operating temp (140F) compared to the starboard motor, when before they were very similar. Once warmed up it stays at the 140F temp as needed. I always...

Pls bear with me as I try to provide as much info as possible to troubleshoot. 88 Sundancer 270, new to me mid season 2013. Very good to excellent condition (inside and out) for age - a true rare find! :) Before I even tried the water tank/pump for operation, I swapped out both head and...

'88 270DA in excellent shape. Boat is stored on triple axle loadmaster trailer in enclosed storage. Boat is wet slipped on weekends when we use it. PO also kept boat on trailer and in storage with minimal usage 7 years leading up to when I purchased 2 years ago. Previous owner before that...

1988 Sundancer 270 3 batteries 4-position battery switch (1, 2, both, OFF) Boat is in heated storage, do I: 1) leave batteries hooked up with shore power and keep charger running full-time? 2) leave batteries hooked up without shore power or only intermittently? 3) remove batteries and store...

1988 Sea Ray 270 Twin Mercruiser 4.3L 175 Ser # 321132 (P) and 321156 (S) New to me boat....want to change the oil.....can't find the oil filters??? Remote oil filters? Thank you.

Took the boat out this weekend and the following occurred. Port motor got up to operating temp with it running at the dock before we even left the dock. Starboard motor temp barely moved even while trolling out to the lake. It wasn't until boat was up on plane that the starboard motor temp...

new to me boat. Previous owner unavailable to consult with. Boat was in a winterize state (both motors and water system) and in storage for last 4 years. '88 Sea Ray270, everything in working order EXCEPT water system. Issue with detail to follow: No water at the faucets, either with pump...

Can u hook up shore power via your extension cord WITHOUT having the batteries hooked up? Is it an open circuit and needs the batteries to close it? If u can do this what position would you have the battery switch on ( 1,2,both,none)? Can this do damage? Do I have to worry about electricity...

Well, I did it. I went out and bought a new used bigger boat. I will post specifics at a later date. This new boat has a 3-battery set up, 2 cranking batteries and one "house" battery. My other boat only had a 2 battery set up and I had cranking batteries for both. The boat I am buying...

I know this is completely subjective, and totally opinionated without factual, but I guess I find comfort in hearing other's opinions. I am just getting into the cruiser boating thing. Used to be a runabout boater. I currently have a '91 250DA in immaculate shape, less than 350 hours, always...
