    1982 Johnson 15 HP repair, help needed...

    Howdy All, I've been working on a 1982 Johnson 15 HP that I bought at a garage sale for quite a while. More like NOT working on it more than working on it but... The short version is that I got her running quite well but after about a minute the bottom cylinder fouls with water. I did...

    Tiller Shifter on "new" 1998 25 HP Merc???

    Howdy All, I just picked up a low-hours 1998 Merc 25 yesterday. This model (25M) has the shifter integral to the tiller handle. Is there a way to put this tiller handle in a "throttle only" mode so I can advance the throttle while in neutral? Also, about mid-way between the very end of the...

    What gas tank fuel line for 1998 25 HP Merc OB?

    Howdy Guys, I just picked up a barely used 1998 25 Merc OB. What fuel line do I need for this motor? I assume the Quick-disconnect connectors are different than those of my Johnson 9.5 that also own right now? When I do some Google searching I get hits with at least 2 different types of...

    1982 Johnson 15 HP - won't start, Carb problem?

    Update 7-2-17 I replaced the fuel pump today and got the same results. She starts and runs smooth as glass for about 3-4 minutes then the idle RMP drops very low and eventually dies. I pulled the plugs right after this happens to inspect. Top cylinder is fine. Bottom is fouled with what...

    In need of help starting my 1987 Johnson 8 horse Sailmaster.

    I see where you are going with this - my research shows that these models, at least the US models, do have the Kill Switch on the tiller handle. I'll try to load a generic pic in this post: WILL, does your motor have the Red Kill Switch at the very end of the tiller handle like the one in this...

    Help with float adjustment on 1974-1979 Johnson Evinrude 9.9hp

    Why do you feel those instructions "can be flawed"? Bending the tab only changes the position of the float with respect to the fuel present in the bowl. The "up" flat adjustment is simple - level with (or 1-2 degrees above, with carb upsidedown) the carb body surface. Here's a page from my 82...

    1982 Johnson 15 HP - won't start, Carb problem?

    Howdy All, I've been working on this motor on and off for the better part of a year and thought today was the day it would run again. Here's some history: Bought it used and did all the necessary and correct things: excellent compression (120/120), new fuel pump, fuel lines, carb kit, fuel...

    1966 Johnson 9.5 Low Speed mixture screw removal???

    Good success today. I was able to pull the low speed mixture screw, and shoot in some carb cleaner. I also installed a fuel filter to hopefully help present this in the future. While I was at it I also decided to dump all the remaining fuel in the tank and mix a new batch. I do this...

    1966 Johnson 9.5 Low Speed mixture screw removal???

    Howdy All, My 9.5 has been running like a scalded dog for the last 1.5 years. Lately however the idle is experiencing that rough "cough" where the motor shakes. I have been slowly adjusting the mixture screw more rich over the last 6 months however the rough idle is to the point where richer...

    Problems with 1982 Johnson 15 HP - recoil starter and carb

    Howdy All, I've been working on this motor for a few months and finally got her fired up in the driveway last weekend. She seemed to idle very well. This weekend (Labor Day) was supposed to be its maiden voyage. Lady Luck was not having any of that however. We never got away from the...

    Oddities in starting procedures: 1963 Johnson 9.5

    Howdy All, I have a very well running 1963 Johnson 9.5, but I am perplexed as to how it behaves when the outside temperature is hot here in Texas, 90-100 degrees. I first got this motor running in winter of 2015. Cold starts are done as usual: prime, choke, throttle to neutral hard stop...

    1982 15 HP Johnson - Long to Short Shaft Conversion issues

    Yes, 11 spline end into the lower. Power Head recess is clear. Also, I will try to attach a pic - there is no slot on the short shaft for the small DS O-ring. CMOS

    1982 15 HP Johnson - Long to Short Shaft Conversion issues

    Howdy All, I found this motor on CL a few months ago and was able to get it for $200. Good spark on both coils and 120/120 compression. Looks like it's been sitting in someone's garage for quite a while. I've been working on "the list" of things to do when buying an non-running motor and...

    82 Johnson 15 - how many Gearcase to Driveshaft seals?

    Howdy All, I'm ordering parts for this new (to me) motor. The diagram shows 2 of these seals (0321480) but when I look AT my actual lower unit I only see ONE. There appears to be a gap between the bottom of this seal assembly and the upper part of the drive shaft bearing itself. Thoughts? CMOS

    1982 Johnson 15 HP - replacing the pee indicator elbow?

    Howdy All, I'm trying to replace the Elbow Indicator fitting (# 0321886) as the hose barb portion broke off the old one. Problem is there is not enough room between the block and the lower cowling for me to 1) get it started and I'm sure 2) enough room to turn the entire assembly to tighten...

    General Starting process, Johnson 9.5?

    Howdy All, This topic may sound a bit vague but I think ultimately it will help a bunch of people. I have a very well taken care of 1966 Johnson 9.5 Seahorse that I've gotten working again by doing ALL the typical things done when buying a used motor (water pump, carb kit, fuel lines, spark...

    1966 Johnson 9.5 - high RPM's, prop disengages

    Howdy All, I took my newly refurbished rig out yesterday and for most of the day the motor ran like a demon, until. . . I had the boat on plane when all of the sudden the RPM's went WAY up and the prop lost propulsion. I throttled way back, prop re-engages. I decided to limp back to the boat...

    1966 Johnson 9.5 SeaHorse T-stat question

    Howdy All, I've got my 1966 Johnson 9.5 runinng like a champ, just waiting for me to finish painting the hull of my Lone Start V 1448. My question: How can I tell if the thermostat is functioning properly? From the looks of the housing bolts I would say it has never been replaced. I do have...

    1966 Johnson 9.5 SeaHorse problems

    Howdy All, I recently found this motor in very nice shape. Had my local Automotive repair guy (who also does work on my mowers, chain saws, etc.) put in a Carb Kit but the darn thing just won't run or idle right. I understand that I just gave you very little information, but I'm hoping maybe...

    Quantity of paint needed for a 14' Aluminum V?

    Howdy All, I recently picked up a 1963 Lone Star 14' Aluminum V-hull in very good shape with the exception of needed paint. I've done my research as to what primer and paint I will most likely use (unless I hear some uber suggestions in this thread) but I have no idea of the quantity of primer...
