    Drying out interior foam (got oily or wet under table pedestal?)

    I use a piece of PVC pipe with the edges sharpened for taking foam samples However if your foam is wet that high up, that is not a good sign. Most likely the "oily" feeling is the bacteria colony

    your transducer is most likely what you found under the motor if 3M goo fixed your leak, then the manifold gasket wasnt intact.

    the plastic washer is a galvanic isolator between the stainless fastener and aluminum. get garolite washers from McMaster Carr the black sticky stuff may have been 3M 4000 UV or other elastomeric sealant

    Volvo penta sx

    look at this fitting specifically (circled in red). is that fitting in perfect shape? is seal item #8 intact? is your power steering cooler plugged? (literally the first strainer in the system) how much water pressure does your hose generate? what is your hose flow rate?

    Transom leak. 4.3l mercruiser with alpha one gen2

    With a good transom, you can hang the boat from the outdrive or let the whole thing stand on the outdrive and never have an issue. The fact the gel is cracked around the transom shield means the transom "squished" enough to crack the gel Good transoms do not squish

    Changing colour of gelcoat question

    Blue handles UV better than Red. clear has no UV inhibitor, which is why you see cars in Florida rust from the top down as the clear coat fails, then the paint fails Keeping your boat stored indoors and properly waxed helps

    1996 Mercury 150 EFI - Tilt cylinder not holding pressure.

    All of them need replacing. However the piston seals are probably bypassing if the cylinder doesn't hold load The materials used in the seals last about 15-20 years max and then they break down

    Volvo 5.7 rough idle

    Then look at how you have the carb set up. If it smooths out above idle, there is an issue with the carbs idle circuit. Either a setting, or debris in the carb passages

    Volvo penta sx

    Impellers do not suck water, they only push water So, start with a new impeller. If the old one is missing fins, find them Additionally, inspect the PS cooler for debris, and check the raw water inlet fitting on the outdrive (where the hose connects)

    Transom leak. 4.3l mercruiser with alpha one gen2

    That crack showing in the gel isn't good. That's an indicator of a soft transom Filling the boat with water was not a good idea a you now forced water into all the flotation boxes, etc. it also submerged your starter, so you now need to pull the starter apart to save it. If the water got...

    Aluminum tubing for a new canvas soft top on a 1989 Starcraft Islander 221V

    I would go longer on the main bow and intermediate bows. I would also sew in an isinglass panel just above the windshield (where your darker blue panel is). then you can actually stand and use it

    1996 Mercury 150 EFI - Tilt cylinder not holding pressure.
