Electrical and Electronics • Re: Pertronix distributors

Thanks, Jeff. I have checked that several times and am sure I am all good. Last night I removed the all the old ignition parts (ballast resistor, brain box). Timing was off. Had to advance it about 2 or 3 deg to get the backfire eliminated. Seems to running good now. Few more lake tests this weekend to be sure.

Electrical and Electronics • Re: Pertronix distributors

Before you start changing things, make sure the plug wires are going to the right plugs. Seriously! The way the wire dive between the manifolds and heads makes it easy to cross a few wires. An insurance company mech playing with mine did that and it took me a while to straight his damn mess out!

Here's the best way to do it: Warm the motor up. With insulated gloves, remove one wire at a time from the distributor cap. If the motor slows, put it back. If it does not, leave it out and keep pulling wires. If you find a second wire doing the same thing, swap the two wires.

Let's hope that's all that's wrong here.

Question for Mike Ray. Years ago you tried Rust-oleum marine paint on a 26 0r 28 I think.
How did it last?

Electrical and Electronics • Pertronix distributors

Just purchased an 82 32 sedan. Previous owner told me he put Petronix distributors in 2019. Could not water test boat before I purchased. Finally got in the water and having lots of backfiring through the carb. Have rebuilt carbs, put new wires, plugs, cap and rotor. I am down to thinking he left too much of the old ignition system in place. Ballast resistor still hooked up as well as brain box. Any advice on what needs to be left. I believe both could be eliminated besides maybe tach wire. Thoughts?

How do I add a signature to my post?

To add a signature to a post you must first create one via your User Control Panel. Once created, you can check the Attach a signature box on the posting form to add your signature. You can also add a signature by default to all your posts by checking the appropriate radio button in the User Control Panel. If you do so, you can still prevent a signature being added to individual posts by un-checking the add signature box within the posting form.

Water may be pooling and falls backwards through ?? to below.

Ahh...drain plugs not tight..thru hull taking in water..loose hose. Have you checked the bilge to see whether you've got water down there...hull crack in a place that's under pressure while you're underway. Forget all the stuff on screws and windows (altho checking window drainage is good general advice).

When you're on plane, bilge water accumulation should be near stern because of angle.

Suggest you have hatches open and have someone inspecting below while you're underway

In my initial post I failed to mention, when the water appears, it’s only when we’re on plane. Again, it’s appearance is very random. I cannot figure out where this volume of water could be stored. We’re in a covered slip so rainwater should not be an issue. I thought perhaps there’s a loose hose connection, or bad hose, at the water tank but I’ve not found water on top, or below, the tank.

I'm guessing you have a screw loose. No, not in THAT way. But above in the cabin roof/flybridge floor and water is migrating along its preferred path. Suggest removing headliner and seeing that you can see. Next culprit might be windows with blocked drains. These thins are often mysterious and hard to track but some detective work will lead you to the source eventually.

If it is a loose (or missing) screw or two, easy to remedy: Caulk the hole, wait til it sets a while, tighten the screw.

Good luck!!

About My Boat Brags • Water on floor in salon

Curious if anyone has had this issue or has an idea where the water is coming from. The boat is a 32', 1989 Sedan Fly Bridge.

We’ve recently had water on the floor in the salon. It’s coming from inside the helm’s wiring and control cables locker. The ‘floor’ in there is wet. This doesn’t happen all the time, and when it does, it’s either barely noticeable, or the carpet is soaked in a 3’ x 3’ area in the center of the salon. The wiring above the floor in the wire locker isn’t wet. The water tank is directly below this locker. No water below the water tank or in the engine compartment. Any thoughts or suggestions?

General Topics • Re: Number of Boats' built ?

David,
As previously mentioned, a change from the original thread subject (in this case - " Number of Boats built?) warrants the start of a new thread subject >> or continuation of a previous one <<. This allows for continuity of the subject. Even an old thread can be picked up on and additional questions / info added. And an old thread may contain the answers (or portions thereof) to a question/inquiry. In the case you asked about just above, you could start/add to a thread relative to "Flybridge Electrical Question"

That flybridge stuff gets exposed to corrosion far more than the stuff inside the cabin. I suspect that's your problem, and I feel for you since 'cause I HATE electrical problems! You'll have to take it wire by wire, switch by switch, to clear everything up.

Good luck!

Jeff

PS: And people ask me why I removed my flybridge!

General Topics • Flight/ upper bridge controls

Thanks For the answer on the gph question…. Now does anyone know how to get the upper bridge switches to work? Is there some secret on Marinettes that I’m not aware of…. I cannot get the ignition to crank or turn off from the upper bridge.

Electrical and Electronics • Re: Removing carbureator

Most gas powered marine generators have electric fuel pumps. If yours does you need to make sure it is powering up while cranking. A test light will tell you if you have power to it.
