    How bad of an idea is this for OB support while trailering?

    Force 85. Trailer is low, and motor hangs low enough that if the T&T hydraulics fail, the skeg is absolutely going to smack the pavement. The trailer doesn't have a cross member far enough back for a transom saver (and I'm not convinced they will actually save anything anyways), so I drilled...

    Am I hurting things by not running WOT?

    80-something Bayliner Trophy 17ft bass boat, Force 85HP motor. Been browsing prop threads lately, where I see a lot of people attempting to chase another 2-3mph out of their boats, along with the common advice of "make sure you're getting X RPM at WOT". I don't have a performance problem per...

    Can I swap factory tilt/trim from Mercury version 85hp to US Marine version 85?

    I have two Force 85 motors. One is a US Marine version without factory tilt & trim, that has had a CMC PT-130 added, which has been a thorn in my side for the past 3 weeks - leaking down internally, takes forever to lift motor then drops it back down in seconds, and still doing it after...

    Has anyone made a diagram for CMC actuator tilt/trim valves/check balls?

    Another case of CMC actuator leaking and not holding position. Pulled it apart, took it down to the local hydraulic shop and got all new seals for it - the 4 small pistons in the plate, the quad seal and spacers, rod bore seal, and the two between the plate and body. Got the seals installed...

    Acceptable to use aluminum plate as outboard shim?

    I moved the CMC tilt/trim unit from one hull to another identical hull, and like a doofus, drilled the holes in the wrong spot...on the old hull, the CMC was mounted as far up as it would go, leaving the top of the plate mounted over the aluminum strip at the top and leaving a small gap between...

    80's Bayliner fuel gauge/sender ohm range?

    '85 Bayliner bass boat..fuel gauge reads half when the tank is full...I get that fuel gauges are just simple ohm meters that say fuel on them instead, but what I don't know is what ohm range they're supposed to be? Are these things pretty standard in the marine world, or are they like cars...

    Finally pulled a fish out of Lake Pleasant, AZ, and it was huge!

    Ok... Fine... Huge only in my mind :LOL: I've been fishing that lake on and off for 15 years, trying all kinds of artificial and live baits, and never once pulled anything alive out of it until today. Took the boat back into a cove, started casting a top water popper and saw a bunch of...

    85hp Force lower unit disassembly? Stuck driveshaft...

    Picked up a boat over the weekend with an 85HP Force with a frozen lower unit. Was going to just swap over the motor from my other boat, but figured I might as well see what's wrong with this one first. Would seem silly to do a motor swap if it ends up just needing a couple bearings and seals...

    Is aluminum much lighter than fiberglass? Metal fatigue on old hulls?

    Currently have a '69 16 foot fiberglass triull bowrider with an 85HP OB...found out it's a bit heavy behind the Jeep. It works, but there is a definite feel of the "tail wagging the dog" at times. For now, I'm towing it with an F350 dually...a wee bit of overkill. I was looking at replacing it...

    Do I need an outboard specific tachometer?

    My boat currently has an old AirGuide Sea Speed tach installed, and was there when I bought the boat. It has never read correctly. Will show the motor as idling around 3,000rpm, and even the slightest bit of throttle application will cause the gauge to peg high at 7,000+ rpm. It's obvious...

    Do I need to seal the dual tube water pump wear plates?

    Parts showed up a few days earlier than expected, so I started tearing into the water pump replacement on the '73 motor today. 85HP Powershift II. I got whole kit with replacement plastic housing, to replace the old cast housing. Turns out the impeller actually looked pretty good once I got...

    What determines HP rating on hulls?

    I'm curious as to how HP ratings are determined for hulls, and if there's a SAFE way to increase that at home? At this point, I'm looking at this purely from an academic standpoint, and just curious for the knowledge. At some point in the future, I may look into building a boat from scratch at...

    Do I really need stands and all this stuff for pulling a 16 footer off the trailer?

    The bunks on the trailer for my '64 Silverline 16 foot bowrider, with a Johnson 85HP OB on it, should have been replaced about a decade ago...it's yet another one of those things that I want to address before getting it in the water this year. I've been watching a bunch of videos and reading...

    Hull number is required to be permanently marked?

    When I went to register my "new to me" '64, I was informed by Arizona Fish & Game that the hull registration number is required to be permanently marked on the outside of the hull on the transom, with the usual stickers not being accepted for this purpose. It was suggested by the lady at the...

    Is a GOOD LU lube pump made anymore?

    I put the question here as it really isn't a manufacturer specific question..does anyone make a high quality lower unit lube pump any more? Seems like I'm replacing the $10 plastic ones typically sold at places like West Marine and auto parts stores at least twice a year because they just flat...

    Is this enough wear on the impeller?

    Motor is a '73 Johnson 85HP Powershift II. Bought the boat about a year ago with no known service history...ran it on the lake half a dozen times, then it sat for about 8 months. Just dropped the LU for inspection of the impeller. It looks OK to me, save for a few minor cracks on the inside...

    Is letting an old outboard sit for 6-8 months anything to be concerned about?

    My boat, a '64 Silverline with a '73 Johnson 85 OB, has been sitting for 6-8 months, without having been winterized. I live in Phoenix, Arizona, so freezing over the winter wasn't any concern (though I realize it's less of an issue with outboards than inboards/IO motors). I hadn't planned on...

    Low amp shore power fittings?

    I would like to permanently mount a battery charger/tender in my 1969 15 foot bow-rider, and also have some kind of permanently installed power connector for it, as I despise having loose cabling in, well, everything. Ideally, I'd like to have a connection outside the boat, rather than snaking...

    Prestolite pump motor, can't find long shaft...

    Went out to do some maintenance work to my new-to-me '69 Silverline with Johnson 85hp outboard. Hit the switch for the power tilt, and...nothing. Worked fine last weekend, and now I just barely hear a faint click in both directions. Battery is at 12.5 volts, and I verified I get 12.5 volts at...

    Champion 828-1 vs 828M plugs?

    Going to put new plugs in my Johnson 85hp V4. I see most of the application charts say to use the QL77JC4 plug, which appears to cross reference to the 828M plugs (which I also see referenced here often). I also found one page that listed the 828-1 plug as a cross, and looking at Champion's...
