    DIY rub rail repair

    2017 I had a loosing encounter with a Miss river channel marker. About 12" of my '96 Larson's NLA rub rail was shattered. The insert was fine. Tocco metals carried a close profile, but not close enough for a partial match around the bow. Full boat rub rail and way too much insert was to cost...

    Tan water after softener regeneration

    This has been an "on and off" issue for years. It's back again. McClean/Fleck mechanical timer. I rebuilt the valve body and replaced the resin +- 10 yrs ago. Not much change. I increased the final rinse time by a few minutes. Still tan water. I use RE (rust eliminating) salt. I guess it works...

    Any stickies for an Alpha II removal stand?

    My 4.3 is winterized, and my back isn't improving. I'll be pulling the drive before it gets too cold. I'm planning to build a removal/storage stand on my favorite $11 Harbor Freight four wheel furniture cart. But before I reinvent the wheel I'd like to see how others have already done it. Any...

    An earlier thread mentioned testing the drive's impeller pump output. Here is the process in my Manual #18. I checked #17 for the V8's and it had the same process and chart.

    1995 Larson 174 SEI Complete Rebuild

    My 174 SEI's first transom layer goes to completely down to the bottom of the transom/bilge, tabbed in completely with a hole drilled for the drain thru both layers. Like Frisco Boaters' "Big Mistake". The second, forward layer is set up, but I don't know why. See pic below. I mention this...

    How bad will this turn out?

    Last week I helped my bud winterize his 42' Bluewater Coastal Cruiser. The marina took care of the rest.....until yesterday. Apparently a fork truck bumped into a jack stand, or the boat itself. The marina is bringing in their insurance assessor. Anyone care to compile a damage report guess...

    How to improve marine VHF SWR?

    When we bought our boat 22 yrs. ago, before cell phone coverage improved to today's stds, I bought a Shakespeare SE2510 VHF radio. I wasn't transmitting clearly, or at all according to my boating friends. I sent it back to Shakespeare who returned it as OK. I bought a SWR meter, and the ratio...

    OAT + Ethylene Glycol screw up

    I didn't know about OAT coolants until I read about them in a Merc. Sterndrive post. And after I topped off my OAT sealed reservoir system in my '16 Cherokee 2.4L with the Ethylene Glycol. I had a warranty coolant hose leak. Maybe 12-16 oz. in the car's 6-8 qt (?) OAT system. Yep, it said OAT...

    Reed switch fuel sender.

    I'm helping my bud shake down a nonfunctional fuel gage and we determined the sender is bad. I changed from a float arm to a Moeller reed switch and it works great, so I suggested he get one. My 9" tank took an 8" sender per Moeller. Their design keeps the float 1" off the bottom of the tank...

    Back flushing '93 Merc 75 hp?

    This is on behalf of my neighbneighbor. He dug mud and lost his witness water pee stream. He installed a new impeller, but still has no stream. I suspect a clogged cooling jacket. Muffs won't clear it. Is there a flush port in his powerhead?

    Thunderbolt IV ==> Thunderbolt V?

    So I'm wasting my Sat. afternoon time pipe dreaming, and probably will be wasting some of your time too. I'm wondering if my '96 4.3LX could be converted from it's Thunderbolt IV to a V. Assuming the graybeards don't answer "Nope", I have questions. First mine is working fine, and hopefully...

    On behalf of my penny-wise, pound-foolish boating bud. His old roller arm cut-out switch is bad, and he shifts w/o the cut-out function because he is too cheap the buy the $116 807962A15 riveted old switch/plate assy. I keep telling him he is in for big repair$ if he doesn't fix that function...
