    Best way to paint a outboard.

    I use a primer called Primocon (Interlux) Sometimes I use the Moeller Zinc primer. Just painted one of my outboards . . .I used a solvent to wipe down the engine & cowling to get rid of the oil/grease, then primed the exposed aluminum areas (mostly on the lower unit) I just painted my 4.5 HP...

    Closed Cooling System on Port Engine Running Hot(ter)

    OK, all set with the Starboard engine t-stat installation. I ran the starboard engine up to temperature with the new t-stat (w/ 2 small by-pass holes). the engine settles in at about 168 per the gauge at idle speeds and no load. So that is the same as the port engine. We are...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    Update: I think I found a crack in the side of the top cylinder. Not that it would contribute to water inhalation, but an issue nonetheless. It is on the intake side and is visible at the middle port. Here are a couple pictures. I made those up/down scratch marks running a needle over the...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    Yes, back in the day, the Johnny's and Evinrude's were the pick of the ocean. Merc's were more the fresh water engine. 1978-79 is when they got on board. My carbon steel shaft lasted 1 season in the salt. The cleaner of the 2 spark plugs was the lower plug. . . . it looked slightly clean...

    Closed Cooling System on Port Engine Running Hot(ter)

    Quick Update: I'm working on the boat today to see if I can get the leak at the thermostat housing resolved. When I took everything apart and was checking the mating surface of the housing to the intake manifold, I noticed that the surface was not completely flat and the t-stat housing could...

    Mercury 7.5 HP Motor Refresh (1969 model year)

    I have a 1969 Mercury 7.5 HP outboard that I use for my dinghy/tender. It seems to be seeping through the gaskets around the water jackets over the past couple of years. So I thought I would do a refresh of the motor and share some pictures of the project. I also plan on a bit of cosmetic work...

    Closed Cooling System on Port Engine Running Hot(ter)

    Starboard Engine Update: I checked the starboard engine heat exchanger, and it needed a bit of TLC, similar to what I found on the port engine. Here are a few pictures, about 6-8 holes blocked on each end of the H.E. This end, maybe 12-14 holes blocked . . . So, I cleaned the ends and...

    Closed Cooling System on Port Engine Running Hot(ter)

    UPDATE: Now that I have the boat out of the water for the season, it is a lot easier to do diagnostic work. So, today, I took the inlet hose and the barb fitting off of the inside transom assembly to get a better check for 'Bravoitis'. Here are a couple of pictures of the hose and insert that...

    Closed Cooling System on Port Engine Running Hot(ter)

    Interestingly enough . . . I was cleaning out the garage this weekend and came across a box of stuff that was from the boat when I bought it 4 years ago . . . and found these :eek: :D Makes me wonder if the PO was chasing some cooling problems :noidea:

    Crazy idea? Marrying stringers

    Not all that crazy, but I would 'sister' the joint on both sides. . . Here is what that would look like (pictures from my thread here on iBoats) , as I did that sort of thing on my 24 foot Cuddy, where the main stringers had only about 1 foot of rot in them and were fine the rest of the way...

    Getting ready for winter in snow country!

    The tough thing about using frame and tarp (instead of frame and shrinkwrap) is that it is harder to get the covering tight enough to shed the snow in all cases. A lot depends on the type of storm . . . if it is very cold, then the snow will tend to shed easily, if it is just below freezing...

    O'Day Mariner Sailboat Restoration

    Boat Renaming ??? I am doing a bit of prep work on the upper portions of the hull, and the boat name is a concern. The name "Little Jeannie" seems like it has meaning to a previous owner, but it has no meaning to me. So, I would like to change the name of the boat, but superstition...

    O'Day Mariner Sailboat Restoration

    3 Coats of anti-fouling done. I just need to do a final coat on the keel and rudder and let everything harden up. Then I can think about putting the keel in the boat.

    1989 MCM 7.4L Bravo Sea Water Pump Impeller Change.. NEED HELP.

    I had the same setup in my 1991 Merc 7.4 bravo. I would just take the pump off via the 2 bolts that the pump and bracket hang from. The top bolt has a slotted hole in the bracket and the bottom bolt is more for holding the belt tension. When re-installing I think I needed a lever bar to tension...

    O'Day Mariner Sailboat Restoration

    3 coats of epoxy-based barrier coating. Now for the first coat of anti-fouling paint . . . The paint I use is ePaint EP-2000. It is an eco-friendly water-based ablative paint that provides a nice smooth surface and keeps the sea critters away. I like the fact that it comes in white. I...

    Used Boat Market Getting 'Thin' ???

    I usually scan the boat advertisement sites every few weeks, particularly in the 24 - 33 foot size range, checking a variety of sites just to see what of interest is out on the used boat market. One thing that I have noticed this year is that there seems to be fewer boats for sale . . . maybe...

    O'Day Mariner Sailboat Restoration

    Update: I have made some progress on the hull prep work. I got the bottom sanded and 2 coats of Interprotect 2000 barrier coat on the hull (below the boot stripe) I think I'll do a third coat and then a few coats of anti-fouling paint, since it is going in the salt. I plan on using the...

    Anyone looking for a project boat ?

    I came across this Crownline 288 BR project boat on CL. Twin Mercruiser 350 Mag MPI w/ Bravo3's Asking $7K, but probably could be had for less. By the looks of it, I would assume it has a bit of moisture in the structure, but who knows :) I would think that you could part out the engines and...

    Portable Vacuum Cleaner Recommendations - for the boat

    I have been thinking of getting a new vacuum cleaner for the boat. The carpet in the cabin seems to collect all kinds of dirt and debris. I have a wimpy no-name 12v plug-in vac that is not up to the task. Looking for something that would be good for carpet as well as hard surfaces and even...

    Bilge Pump Wiring

    My bilge pump bit the dust during one of my recent outings with the boat. I accidentally left it on while anchored and it seems to have burnt out the motor. When I checked on it this past weekend, I noticed that there was an indicator light illuminated inside the instrument panel switch that...
