I'm having an issue with high voltage and motor dropping cylinders (power). Just had both switch boxes replaced (one tested bad) and the stator checked. Stator tested good. My mechanic indicated two cylinders were dropping out. BTW, compression at or about 110 on all 6. After the repair, it...
It seems that there are several 3-wire replacement trim motors available for the older V6 Johnson outboards. I have have a 1980 200HP Johnson and I'm needing to replace the motor. Does anyone have a preference? They can run from $70(Ebay)-$300 elsewhere. Iboats offers the Mallory, Sierra, or...
It looks like many parts are interchangeable? I can buy this 1982 150 locally in hopes of using some of the parts on my 200. The 150 overheated, but all of the ancillary parts are there except for the lower unit. What would be a fair price for this parts motor? Will the carburetors interchange?
I have an extreme difference in temperature readings between the port and starboard banks on my 1980 200hp Johnson. In cool 65 degree outside temperature, using a laser temperature tool, the port side is running at about 92 degrees, starboard at nearly 150 degrees after 15 min. idle. Here's...
Well, I have everything running well on this old motor...got rid of the rough idle, but now I'm concerned about potential cooling/water flow issues. I replaced the impeller several months ago, but now I'm seeing no water coming out of the exhaust leg (in the middle), only light smoke...
Hi All:
I'm working through a very rough idle issue. I have rebuilt the carburetors with kits and replaced one fuel pump. I feel comfortable that the fuel system is now solid. As background, compression is 90 lbs. on 5 cylinders and 95 lbs. on one. I'm moving to the ignition area supported...
Can I get some advice on installing/removing pins in the waterproof connectors on a 1980 200HP Johnson? I purchased a couple of new coils and would like to install with new pins into the original connectors rather than splicing. The original manual I have shows some specialized tools, but I...
Howdy:
I need some clarification relative to the installation of the impeller wedge on a 1980 200HP Johnson with the new style pump housing. The plastic wedge, which acts as the key, goes with the narrow (tapered) end forward while turning the shaft clockwise...correct? This makes total sense...
Well..I think I just recorded some bad news. I picked up a motor that had not been run for a number of years. Before spending much time on a tune-up, etc., I took a compression reading on all six cylinders. The readings varied from a low of 75 to a high of 90 on all six cylinders with most...
No down tilt/trim action! Trim rams will not go in either. I feel like it's not an electrical issue since I've gone directly to the blk, grn, and blu wires feeding the trim/tilt motor. Motor runs fine in both directions. Tilts up, but not down. I've tried to push on the tail of the motor to...
Hi Everyone:
I removed the lower unit for a seal replacement on my 75 HP and noticed there is no "Lower Water Tube". This is a plastic sleeve like doodad that fits on the water tube just before it goes into the top of the water pump housing.
Currently, the water pump housing is a 474060 and...
Can a person run two Batteries in parallel with these motors? Sometimes we anchor and swim several hours using the stereo and accessories. Will the alternator charge two batteries at once or should I just have a completely separate battery?
I need to get back to this project. It's almost Spring??? Last year I installed a new tachometer, but it seems to read significantly lower than it should. Possibly as much as 25%? It's a 20 pole, but I set it to the 12 position. The documentation I have (manual) shows that a '76 75 hp is a...
While replacing the bendix, my starter (prestolite) came apart and I believe I have the 4 brushes out of place now. When I put back together, it has very little torque--like 1/2 power?? Are the brushes from each set of poles opposite of one another, if that makes any sense? The manuals make...
Well, my 1976 75hp is still overheating. After about 10 minutes the tell tale quit delivering water. I have replaced the impeller (twice) and then the thermostat. The water pump housing looked good and then I ran water from a garden hose up the tube to the top of the block and it apppeared...
