    That is looking good, especially for a 10yr old BIII that stays in the water. I have always tried to keep the OEM glossy black finish on my drive, but I think if the boat stays in the water an antifouling finish is the way to go. Someone may have mentioned already in one of your other threads, but there should be a 1" gap between the bottom paint and the outdrive, mainly due to any copper in the paint. Plus, aesthetically for us boat geeks I think it looks better (you know, on that boat bottom and outdrive that is underwater where no one sees it).

    Yea I too prefer the glossy factory finish, but the thought of loading/unloading every time I want to go sit on the boat is unnerving. I'm going to pull it out more often this season, if for nothing else than to check and clean underneath. BIII looked ok because P/O keep it out of water and never had the bottom of hull painted, much less the O/D. The marina I had do the bottom also is responsible for NOT leaving the 1" gap. I ask about it and they looked at me like I'm crazy. Most marinas around here don't do that type of Industrious work and send their boats here, where I had mine done (It's also my home base slip) Point being, this isn't their 1st rodeo, you'd think they would be aware:huh:.

    Nice looking paint job. Only problem I see is that every time I look at the pics, it looks like a Volvo outdrive! :smt001 (I know, you're not done, yet)

    1"... Ask the marina what kind of paint they used. Maybe they used a non-metal based paint on the hull.

    Update- about 4 coats of Interlux PRIMICON (silver) have been applied. It took 3/4 of a Qt. can plus half of a spray can to do the job.
    Yesterday before the weather dip I managed to get a coat on of the Interlux PACIFICA anti fouling out-drive coating. Prior to opening, I took the gallon to Sherwin-Williams to have it properly shaken (after Lowes refused?). "This has to be the heaviest gallon of paint I've ever held" said the nice guy behind the counter.
    Man that stuff's thick ! The label says "do not apply thin coats". NO CHANCE OF THAT!
    It's NOT going to win any beauty contest, luckily, it resides under the waterline once splashed !
    Another few coats, trim tabs too, and I can button the gallon can til next season, hopefully.-
    It's turned winter again overnight, pics when it thaws..Jeff

    You'll have to let us know how the interlux Pacifica works out. I haven't heard of this paint before and have only used their trilux II, Usually have to repaint every 6 months.

    Application of the Interlux Pacifica is complete.
    New Z's. It's not pretty, nor does it attempt to be..

    It's made to protect the drive, your not going to get it to flow out smooth and perfect like a spray paint. I would much rather have that than a corroded mess in a few years - good job.

    Looks good... well, as good as AF paint can, anyways! If you haven't already, don't forget to open up your pitot hole.

    agreed, as much as I love the factory finish, it just wasn't conducive for leaving in the water, probably still not. I'll pull her out more often to see how the barnacles are doing... The feeling I got when hauling her out last year, seeing my O/D covered in marine growth.............. don't want that again.......

    The pitot hole is the speedometer pickup. It's a tiny hole on the leading edge of the outdrive just below the cavitation plate. It can get clogged with debris and cause the speedometer to quit working or in your case maybe the thick anti fouling paint. Just use a small piece of wire to reem it out.

    The pitot hole is what drives your speedometer - incoming water pressure compresses air inside a tube, which in turn, moves the needle. There is a small hole on the leading edge of the drive, just a few inches above the gear case (torpedo looking thing). Take a small drill bit and, by HAND, stick it in and turn it around. You won't damage anything - it's all metal - and the hole goes in about 2" (give or take). You'll know because the drill bit will stop dead when it hits the end.

    EDIT: Bill beat me... :smt001

    Pulled Mountains to Sea out yesterday.
    It's been 6 weeks since she went in. 37 hours of run time, mostly at 6 knots.

    As you recall, I've prepped (Primicon) and painted the outdrive with INTERLUX PACIFICIA.
    Although the hull has a nice green coat of slime, and a few BARNACLES :( near the waterline, the

    OUTDRIVE LOOKS GREAT !

    Not one barnacle, it looks as it did when I put her in.

    WINNER !!
