    Source/question for a crossmember?

    3 x 3" box with a drop, rail to rail is 53", bolt hole distance 49", total length 51" Yeah I found a good bit but nothing exact. Not a big deal to cut it down. I had already bought some zinc primer planning to sand and coat a few spots on the trailer and lift before they get out of hand.

    Source/question for a crossmember?

    Noticed my rear crossmember had some significant rot. it's a bolt on but I can't find the right size. I figure I can cut it down and drill a longer one but would be worried about the galvanizing. suggestions? anybody know if I can get a custom one made non local (guessing that won't be worth it)

    2012 3.0L TKS runs great with muffs, but slow on lake...

    I'm talking about all connections everywhere, not just the plug wires. I already mentioned how to test for misfires under load. At 3k rpm you might not hear much. your fuel pressure sounds fine. I'm also in the minority here where sometimes it is the coil.

    1979 Cobalt 18DV w/ MerCruiser 260 and Alpha 1 - No Raw water to engine

    2k on muffs might be enough to overheat. Pull the line to the stat and see if you're getting flow

    2012 3.0L TKS runs great with muffs, but slow on lake...

    Doesn't sound nuts...sounds electrical. Though could also be that the carb is fueling differently because of the angle. Any change when hitting a wake? Have you checked spark at speed? Rereading the thread I see that the spark was checked at idle, but not under load? I'm broken record about...

    Are we sure that's not engine noise?

    thinking of a Delco EST ignition system conversion but have a few concerns....

    Huh, you have points? I'd stick with them. Throw a spare set in the toolbox and you won't be stranded on the water. Assuming you can get a pertronix or something for the OMC though if you wanted to? Or even convert to a TB IV if you find a used setup...

    Testing my temp gauge

    for a standard faria/teleflex gauge. I believe some vdo gauges (maybe others) have a different scale

    2012 3.0L TKS runs great with muffs, but slow on lake...

    Yes shutters=flappers. Maybe time to throw a vacuum gauge on it? Could show some subtle problems. It would also show an exhaust restriction, which might be tough to diagnose otherwise

    Stupid me, no oil

    I had a hard time finding ones that had enough thread on them to cut down. Online the shipping and minimums were a killer. I ended up stacking like 20 washers on each bolt with the intention of doing it right at some point LOL...Classy!

    Stupid me, no oil

    They actually just offered me a $20 discount on a new one, while blaming me for the corrosion. Interestingly the new ones are SS and they don't sell aluminum now, so obviously I'm not the only one with the problem. I may get another, because it was fun to have and they seem to be the only...

    Stupid me, no oil

    FYI, Hardin told me to go pound sand and they don't warranty anything against corrosion. Also, went through about a 1/2 qt oil so far this season. Very small amount in bilge, but I'll take it as a win.

    Carb tuning

    I've tried changing the holes on the linkage with zero effect, so that's interesting. Of course I don't remember if this has always been present or just since the big dunk.

    Carb tuning

    FWIW, that first tune is what I first went with and it was CRAZY lean. Also, IIRC the factory weber has 3 step metering rods vs the 2 with the 1409. Interesting. Mine has been doing that for a while, only bothers me when trying to pull a skier. Have been planning on taking it apart, but maybe...

    Help with early 80s mercruiser 140hp

    Checking timing, points and compression is very basic troubleshooting. Sounds like you've eyeballed 2 out of 3, so they're almost certainly off

    End of Season oil changes?

    I always intend to do it at the end of the season, and then end up doing it right before I'm trying to launch.
