I have a 2004 Tohatsu TLDI 90B and I have heard they are sensitive to the type of tcw3 oil they use. So much so that they have to be reprogrammed whenever you want to change brands/types. I am out of what the previous owner used and can't remember what it was. I have always used Penzoil xlf...
I broke my port stern bracket on my 1973 115 HP Johnson 115ESL73M. The part number I found is 0386005 and is not available. I found this is a quote from ezeke on these forums. "The part # is 0319448 or 0386005. It's called a port stern bracket." I have been able to locate several of the...
Does anyone have a source for a reasonably priced fast idle lever? This should be a $5 part and it is $50 everywhere. Iboats even shows it as unavailable from my phone but I know they have them for $53. I know I know, welcome to marine parts but seriously. There has to be some out there for...
I had an overheating problem last week so I checked all water passages, replaced the vernatherm and installed a tell tale in the top of cylinder #1. Runs cool on muffs but the pee stream is weak and sputters. I am not sure if this is normal but I doubt it. I am thinking of dropping the lower...
My 1973 Johnson 115ESL73 115HP has just started overheating under load. This just started 2 days ago after a day of fun tubing/cruising with the kids. All good all day long. The last 30 min of the day I was making a sustained high speed run near maximum rpm for a little thrill as we ended the...
Can I fit a modern tachometer to this engine? I believe from searching these forums that any 12 pole 6 pulse unit should work and possibly plug right into the 1990 control box I am using with it. Some place I read it is difficult to make non period tachs work so I was looking for expertise here.
Stupid question for my 1973 115 Johnson model 115 ES L73 what is the type of gear lube that goes in the lower unit the manual says OMC gear lube gearcase lubricant or type C will standard West Marine high viscosity lower unit oil 8090 weight suffice? It is a powershift two motor.
My 1973 Johnson 115 model 115ESL73 trim tab bolt will not budge. I have applied heat, penetrating oil, ice an impact driver and an air impact wrench to it. The trim tab will rotate through its range tapping it with a small hammer but the bolt does not turn. I rounded off the head but was able...
Can I inspect the impeller on my 1973 Johnson 115 without replacing any gaskets I have looked through the book and I am still unclear if you can inspect without breaking any seals. Also is anyone familiar with the correct water pump kit for this engine I'm thinking anything pre-1978 but would...
Do any of you old salts have a trick to verify the accuracy of the timing indicator without a dial indicator. This motor has been recently rebuilt and who knows how well they did the reassembly. My first thought is to simply put a dowel into the number 1 cylinder to verify top dead center and...
Hello all. I finally received my factory service manual for this engine and it doesn't give a torque value for the prop nut. From what I could find searching around here it looks like the general consensus is 10lbs min and 12lbs max since I have the nylon spacer. Another value was given as...
When I recently bought a 1970 Chrysler commando 15 foot center console boat. It had a 1990 Johnson 88 hp on it which I just swapped out for a 1973 Johnson 115. My question is this, the 88 only had the top two mounting holes drilled through the transom albeit also through a metal plate capping...
Well last night I bought a 73 Johnson 115 to replace my blown 1990 88 SPL. Compression is good at 112 112 119 and 114. The lower unit oil is a little cloudy but still looks like oil not milk. The transmission is silent in forward and reverse and it seems to be in decent shape overall and runs...
I just bought a 1973 Johnson 115 the only thing that seems to be off about it is that the propeller slides more than an inch fore and aft on the prop shaft upon which it snuggly fits. My question is this. should it be shimmed into place or is it a free-floating propeller?
Hello everyone. I just bought a new to me 1970 Chrysler Hydro Vee Commando ( I think) model 522. It has a Johnson outboard but claimed as a 1988 90 HP but I believe it is a 1990 88 HP. Anyway it is a Model# J88MSLESA Serial# R 08533310 It is a USA model and I am looking for a factory...
