    2003 Sunesta 210 - can’t access fresh water pump

    Yup . . . tight access. Looks similar to my situation. I'd be putting pillows and blankets across the engine and battery to get at it.

    1990 Sea Ray 270 Headliner Replacement

    Got any pictures to share? Those should help with responses. I replaced the headliner in my Formula 330. It was really 'fun' :rolleyes: The first thing to do is figure out if there are sections to the headliner and how it is secured to the ceiling. You may have to get creative in taking...

    Blue Sea dual battery troubleshooting

    My thoughts are 1 dead battery. Are the batteries kept on a maintenance charger?

    Quadrajet Secondaries Problem

    One thought that comes to mind is that you did not run the boat much last year. So, assuming there is older fuel in the boat, and perhaps it sat in the carburetor untreated over the winter? You would need to know exactly what was done during the winterization to determine this. Before giving...

    engine swap need to find right prop

    I would go down a couple of increments on the pitch . . . so maybe a 15(dia) x 13(pitch) 15" diameter is actually a fairly big prop, so you should be much lower on the pitch. So, maybe even 11" pitch. Your situation reminds me of when I had one dead engine on my twin engine boat. I tried...

    Merc Sterndrive 3.0 Pressure test is holding steady at 7psi, should I be concerned?

    Boats will do that, particularly if you are working on an older boat/motor. On the OD pressure test, usually the concern is if the pressure does not hold . . . :D

    2003 Sunesta 210 - can’t access fresh water pump

    Greetings, welcome to iBoats. Maybe post a picture (or a few) of the tank & pump. My initial thoughts are to remove the tank to get better access to the pump. My current boat has a similar situation . . . there is an inverter in the way, so I can barely reach the pump. I had to replace the...

    Is it possible to put the upper half of the sterndrive on first? Or do I need to put the whole drive on together?

    No, I have Bravo outdrives, so they go as one. Not sure of the advantage of doing an Alpha the way you described. It is nice to know you have the outdrive together properly before you install it to the bell housing.

    Is it possible to put the upper half of the sterndrive on first? Or do I need to put the whole drive on together?

    It is often tricky to get the gimbal bearing to align (pivot) so that the drive shaft meets the coupler properly. I often grab the u-joints (to the extent that I can reach them) to help the drive shaft find its way.

    New Cobalt 23LS

    It sounds like the only thing left to do is go get your boat. :)

    New Cobalt 23LS

    I never understood what the LX signified . . . The 7.4L engines 'shine' coming up on plane . . . probably better than the 454 MAG, since those engines are more suited for the top end of the RPM range.

    New Cobalt 23LS

    Serial # 0K147398 comes up as a Gen5 7.4L https://www.perfprotech.com/mercury-marine-parts-catalog/search#/diagrams/folder/24554328171979

    New Cobalt 23LS

    No difference . . . Bravo 1 outdrive, 7.4L MPI engine. In the 1996-97 time frame the 7.4 and 454's were the GM Gen6 version, which used roller cam/lifters. Better than the Gen5 IMO.

    New Cobalt 23LS

    OK, so the video in the advertisement is not the exact boat, but similar. :unsure: Usually in Mercruiser 'speak' the Magnum engines are labeled and referred to in cubic inches. So, a 7.4L Magnum is usually referred to as a 454 MAG. So, it is a good assumption that it is the standard 7.4L oval...

    New Cobalt 23LS

    EDIT: The engine is a V-P 7.4 Gi as shown in the video. . . https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwi15vPXmNT_AhW-L1kFHcTHCZwQFnoECA0QAQ&url=https%3A%2F%2Fpubs.volvopenta.com%2Fpublications%2F7740288&usg=AOvVaw2XOhAZWTuqIFKBKEkaFBmW&opi=89978449 Be careful...

    Water in Oil (Again) Head Scratcher

    I might have missed it, but when the engine was rebuilt, did the shop put a new camshaft in the engine? Just wondering if there is too much valve overlap.

    Mercruiser Spark plug broken

    IDK . . . I think they used to be around $100. Probably more now.

    Replacing Carpet with Laminate in salon

    I did the cabin floor on my 33 foot Formula (330 SS), pulled up the carpet and replaced with vinyl laminate flooring. I'd say about a 6 on a 10 scale, if you are handy. When you pull up the carpet, you will be able to determine the condition of the sub-floor. That's when a can-of-worms could...

    Yamaha 4 HP, cranks, runs, but fails to come back from idling down to shift gears

    I have the Yammy 3 HP, which is pretty much the same thing. Finicky motors for sure. I think the reason is that they are 1 cylinder engines and as such not really designed to go low RPM. After much fiddling with the carburetor and using carb cleaner, I've found that I needed to shift into...
