    Lower unit oil

    Coated paper gearcase gaskets are the right ones for most applications. The nylon can be too hard to seal well. I never seriously tried the oring ones. You need to dig the remains of the paper ones out of the gearcase when changing the oil, as multiple partial gaskets can leak. Amazon and...

    Bumps in Gelcoat - blistering?

    Let it go until the spring. They may dry out. I get those in the cockpit, when it is covered by a wet cushion. They dry out after a while I would still recommend the barrier coating. I did 3 coats of pettit epoxy barrier coat. You mix it(50:50) roll it on and recoat after the time...

    Glastron SX 175 Gas Smell

    Try the gasket dry. If she leaks, put the dressing on it. The dressing is a non-hardening, fuel resistant substance. Seals real well.

    Glastron SX 175 Gas Smell

    "Permatex gasket dressing and sealant" is fuel resistant. I have used it to seal the sender gasket, with good results. Coat both sides of the rubber gasket and tighten the clamp screws. If in doubt, replace the gasket with new.

    Check engine alarm

    Your motor will have the high speed jets in the carb bowls, behind the brass plug. I have heard they are hard to get. You might try a salvage yard or flea bay.

    Change prop or leave as is

    1 inch of pitch will in theory get you to max RPM. However, adding load, say a cooler will negate that RPM. I think you are at max performance.

    1990 90 hp Mercury. Beeping when key turned on.

    What does the owners manual (internet) say the beeping is? Probably an oil injection issue. That motor usually comes with just the engine oil reservoir. Is the float level sensor working? I believe it should ground when oil is low. A steady tone is overheat. Obviously you should premix...

    1977 Baja on the cheap

    That motor has a lousy prop on it. Unusual for a performance boat. I cannot tell if it has power trim. If not, it will not be a performance boat. Is the floor soft? If so, that indicates it needs replacement, and perhaps the stringers as well. Also check the transom for delamination and...

    Yep, it's that time! :-(

    It used to take me all day (short days in December) to pull the boat and winterize my MerCruiser 4.3LX. With my OB motor, I can be on that scotch by noon!

    Gear oil for 15 hp Evinrude outboard

    Gee, put the gear oil in the kitchen before you try to change that. Wifey will like that a lot.

    Yep, it's that time! :-(

    Gee, clean the spark arrestor, grease the zerk fittings, spray the engine block with corrosion guard, change the engine oil and filter, change the water separator, grease the steering rod, pull the prop and clean the propshaft, remove the barnacles. I miss anything?

    We always found a socket from a socket set, that would fit well enough.

    Does this miss sound like fuel or ignition to you ?

    Sounds like lean sneeze. It may run better under load.

    carpet

    A light color. There are a whole lot of indoor/outdoor carpets avail. any will work. I would think a low nap would be coolest, in light blue, beige or teal, which are good colors for boats. Of course light colors show dirt more than dark. However, I/O carpets are real tough and will stand up...

    Winterizing suzuki df25a?

    I use boat trailer wheel bearing grease for everything, since I boat in salt water. It is overkill for anything not wheel bearings, but it is maybe a $1 more for a cartridge, and I only need one grease gun.

    1978 thunderbolt 1150 remove roller bearing

    That is one of the gears from the gearcase, right? Pinon gear perhaps? You might tell us.

    change steering shaft

    This is a real good question for the MerCruiser forum. I am not an expert, but I think you are SOL, unless you pull the motor.

    Winterizing suzuki df25a?

    Grease the steering and tilt. Usually there are some zerk fittings. I use some corrosion guard on the block to keep any rust at bay.
