    Any tricks for wire corrosion

    Hi, I am working on the wiring on my boat. Some plugs got wet and the wires started to tarnish. No green corrosion, but the wires do have that black oxide coating on them. 1. Is there some kind of crap I can buy that will soak up the wire and stop the corrosion? 2. How long will these wires...

    I will settle all arguments once and for all! I BOUGHT A DYNO

    Ok, so when I saw a marine dyno for cheap I couldn't help but buy it. Yeah I know a thousand bucks is a lot for a tool for working on a boat, but a new one is 14 grand around here - so I had to buy it. Its a dynomite water brake actually meant for measuring power levels, so now I can actually...

    Ignition system common failures? 1994 7.4GL

    Hi, this one has me stumped. Seems like im better at diagnosing efi motors than the carbed ones. I don't know the exact model number, because the sticker is long gone, but it is a 1994 7.4GL. The ignition system is NOT the EST, or the EEM version. Here is a pic of the motor: This thing...

    crank question

    Hello I got a bunch of free motors (3x 20MLHU, 1x 30MLHU). the 20s are pretty trashed, but I was thinking I could make 2 good ones out of 3. All the crank needs is the bearings on the crank replaced. How do I go about doing this? pic of one of the cranks: the 30 hp motor has good everything...

    Mystery corrosion. 2007 F150

    I found a free motor at the scrapyard (2007 F150). The lower unit looked good, without any corrosion at all, so it was a no brainer to load it up. It was partially disassembled, but with all the parts there. The oil was all milky. I pulled the head and found this: Funny that the anodes aren't...

    Need seat recommendations

    Hello! The seats on my tuffy are all ripped. I can't decide which ones are better. I'd like to stay within $200 USD if possible. Everyone says the centric II SAS is the best, but they don't make those anymore. So option 1 is the tempress probax. Looks nice, although the thing that puts me off...

    Boat TLC questions

    Hello! Well, the boat that stupid me tried to bring on a flatbed car hauler is finally here... albeit not on a car hauler. A boat trailer did the trick. Anyways, I thought I was buying a boat that was totaled for being rear ended so the engine was all messed up and the bow of the boat as...

    Question about LU rebuild + getting ripped off on sale.

    Hello I am selling my boat (the tuffy) and it seems like I have milky oil. A buyer asked about it and I, like a dummy, told him it was milky when I drained it a month ago. Well now he calls me and asks me to drop 4k on the price so he can get a brand new lower unit. I'm pretty sure everyone...

    3.0 pistons squeaking... doesn't sound good.

    Hello Was working on a friends boat today, after he overheated it. He didn't even know that the outdrive had an impeller. I pulled the drive apart and the impeller was NLA🙄. The pieces dropped down into the intake grate so I got lucky there. Tried to start the thing after putting the new...

    Battery combiner sudden load question

    Hello everyone. I was thinking about building a battery combiner for my boat to have the engine charge my trolling motor batteries in between fishing spots. I typically sit for about 10 min at one spot and move to another one so I was thinking I could get some juice in on those runs. I am going...

    General MAP sensor question

    Hello, I have a fairly general map sensor question. The engine is a 2008 DF200, but that is not really relevant. My map sensor was showing 117 kpa pressure when I removed it in my hand. I tried blowing or sucking on it but that does not change the reading. After tapping it against the intake...

    Outboard repaint - need suggestions on materials

    Hello I needed a new hood for my 'zuke, so I got one for cheap, but it was real sun faded, with the paint all flaking away. I sanded it and painted with merc rattle cans (took about 7 of them) and it did not turn out well, quite dull, and I must have not sanded enough, because the texture was...

    Best gelcoat guns?

    Hello everyone I need to do some gelcoat repairs on one of my boats. I tried a preval and it turned out like garbage. The thick gelcoat doesn't go through them very well and if you thin it down a lot it lays down very thin, and you end up needing tons of those sprayers. Besides, if you run...
