35 HP Gale WOT 7MPH???

Re: 35 HP Gale WOT 7MPH???

maybe it will correct itself when i tune the carb. any suggestions?

I doubt adjusting the carb is your problem, I'm guessing here but I would say somethings not right with the way one of the coils is hooked up???

Re: 35 HP Gale WOT 7MPH???

i dont think so, its exactly the same as the one i pulled out, and mirror of the other coil that was good.

Re: 35 HP Gale WOT 7MPH???

I think the key shorts the 2 black wires from under the flywheel together to kill

I found this through a google search, could it be the key switch?

Re: 35 HP Gale WOT 7MPH???

Yeah, it could be the switch. The two black wires go to the M terminals on the switch. When you turn the switch off, it shorts those two wires together. Now, that outboard also has a vacuum cutoff switch, and one of the black wires from under the flywheel goes to it. A second wire on the same terminal of the vacuum cutoff switch goes to the key switch. The other black wire goes directly to the key switch. If one of them is missing, only one cylinder will get shut off, which is what you're describing.

In the earlier years, you had to kill those engines by using the choke. That still works, until you sort out the wiring problem.

Remember that this a an old engine, and wires get frayed and broken. Trace those black wires carefully. On my 58 Johnson 35, one of them was broken off at the external wiring harness plug. Very annoying.

Alright, got the needles all cleaned up and looking good, remounted the transducer, and new batteries in the GPS for a hopefully higher speed reading. Tomorrow at 7am were going out to tune in the carb. Finally I will have an on the water report for you guys. Thanks for all the help guys. I am pretty confident It will be much faster this time around

Re: 35 HP Gale WOT 7MPH???

And here is the report. after a little adjustment of the high and low speed needles and some linkage changes, we were able to get it up to 16 MPH. Im fine with this, its way faster than my 12 footer is. At anyrate the only things to do from now on are remove the sub floor and apply gluvit, and get that pesky generator figured out. As far as the generator goes what do you all think would be the best course of action. is there a generator kit than i can just swap in/out with a rectifier too?

Re: 35 HP Gale WOT 7MPH???

who made the generator? theres usally a rebuilder around who can fixe'em up, I had lots of old kholer motors that had starter and generator combos and they were always easy rebuilds. (for a rebuilder)

It should go faster than that, but you'll sort it out eventually. As for the generator, you don't really need it in the first place. A charged battery will start that outboard dozens and dozens of times. Just use a battery charger on the battery after you get home and you'll be golden. Most people never had a generator on those Big Twins and they did just fine.

Once you get the boat sorted out, try it again, and report back on what you hear from the outboard. An RPM reading at wide open throttle would be good, but it's hard to find a tach for a magneto outboard. Tinytachs work good, but we'll help you out in any case. I'd expect that outboard to push your 16' aluminum boat at about 22-24 mph. We might be able to get it to that with just changing the trim and stuff like that.

In that case the engine should gain some power once the drive belt is removed from the generator and stop some parasitic draw. I would say a generator with worn bearings could slow things down a bit??

Re: 35 HP Gale WOT 7MPH???

i cant imagine the generator would take all that much away from it. its kind of trial and error still with the linkage stuff but i was thinking 16 was a little slower than it should be. Also I kind of wanted the generator because I have a Stereo, fishfinder and lights and VHF runnin off the system as well. I mean i guess it wont take all that much power to run that stuff, I would just like it to work. Ill go check on the make of the generator in a few mins, but before I do that do I NEED that specific rectifier? They seem a little expensive, is there some kind of universal one or am I roped into spending a hundred bucks

Re: 35 HP Gale WOT 7MPH???

Just a few pictures to show you all what I am working with. Mind you there were no seats or accessories in the boat prior, also I added that bilge pump with the thru hull fitting. Not bad for trading an 80$ .22 rifle for a side by side shotgun for what you see here

Re: 35 HP Gale WOT 7MPH???

Also it is an Autolite GJG 4001M 7M Generator

Re: 35 HP Gale WOT 7MPH???

but before I do that do I NEED that specific rectifier?

Rectifiers are used with alternators to convert AC power to DC power. DC generators require a voltage regulator. Not sure what you are looking at for $100. Do you have an OMC p/n?

Nice rig from your gun swaps! Agree that it should do better than 16MPH. If that speed was determined by a water-tube speedometer, it is probably wrong. Hand-held GPS is best. Most important is the performance of the motor. While it is no speed demon, it should plane your boat easily and provide speeds around 25MPH. You need to make sure ignition advance and carb linkage is synchronized and carb throttle valve opens fully. Remote control linkage could be limiting the results also. Keep the questions coming. Plenty of help available.

Re: 35 HP Gale WOT 7MPH???

381538 is the part number. It was under rectifiers but its a regulator. I can find them on maxrules.com and 2 on ebay. Ill have to get a tiny tach to see what im turning and check the linkage again. Oh and the speed was on my garmin handheld

Re: 35 HP Gale WOT 7MPH???

Oh, yeah...don't forget to push that choke all the way in after the engine warms up. It's easy to forget when you're trying the boat for the first time. That'll slow it down. I know. I've done it.

Also, show us a photo of the prop in relationship with the bottom of the boat. Finally, experiment with the tilt of your outboard until you find the position that gives the best performance. Little things make a big difference.

Re: 35 HP Gale WOT 7MPH???

OK so were still making some head way. The choke wasnt on or anything i was using the electric choke so it was on or off. But i found a linkage problem! So lets use my hip-bone connected to the leg bone descriptive skills. For lack of better terminology the throttle is connected to these 2 gears that connect to some long vertical pole that hooks to the throttle cable. Well on that pole there is a pin that sticks out of a key way of the gear so it doesnt slip, that pin was broken. So I pushed out the remaining piece of plastic, drilled a hole thru it, and fit a stainless 10-24 machine bolt thru it and cut it to length. here are 2 pics that show what i cant really elaborate haha.

This is it fixed

Maybe that is why I was not gettin Full Throttle?

 

[CATransplant]

Re: 35 HP Gale WOT 7MPH???

Could easily be. Look in the carb throat with the throttle in the wide open position. The throttle butterfly, behind the choke butterfly, should be absolutely horizontal.

Great find! FYI, I believe that plastic (nylon) pin is p/n 0304155 (may be superceded) which should still be available because it was used on many millions of OMC motors. Also, it has flat "ears" on both sides for maximum contact in the gear slots. You made a good fix but your SS bolt is much harder than nylon and may damage the aluminum gear. Check the armature plate for easy movement and lube the linkage good. Gotta think it's close to being right now!

EDIT: As suspected, p/n is now 0329197.

Re: 35 HP Gale WOT 7MPH???

381538 is the part number.

A few bucks cheaper here: http://www.marineengine.com/newparts/part_search.php

I hope you have the parts catalog because I do not. Maybe another member can verify.

Re: 35 HP Gale WOT 7MPH???

CAT, i looked at the carb throat at WOT and it is horizontal, just as the choke with no choke so thats good. come to think of it when my dad was adjusting the linkage and holding the carb wot i think it went 17.1 but I didnt put 2 and 2 together till now. And the trim is just about 90 degrees the bottom of the hull and at the right height. before it was a little swung back so this might help as well.

Willy, thanks for those part numbers. i see what your talking about with the 2 sides for that pin. Also I might just bite the bullet and get a new reg with some extra money I am making doing a roof tomorrow. Or maybe Ill just get some paint for the trailer, or both who knows haha.

At anyrate i will keep you all updated. Thanks again for all the help guys
