I wanted to see what you guys would price a perfectly running, great compression, 1979 Johnson 150 at with working tilt and trim. The motor is strong but the boat its on is starting to scare me (Hull wise). Let me know what you think. Thanks.
I have a 1979 Johnson 150 that I got running for the first time in 12 months. I did the proper starting methods when you have had a motor sitting for a long time. To my surprise it started right up and runs like a top. The only problem I am experiencing is a small poof of smoke randomly (once...
I have a budget of about 1500$. I bought a 1985 19' Ebbtide DynaTrak SS with a solid 1979 Johnson 150 on it but the boat was full blown rotted. Not a single spot of the boat was solid. I don't want to invest that much time to resto. that boat although I have bought the supplies. I figured it...
I am about to purchase a solid restored 1988 17' Bayliner Cuddy with a blown 85 hp Force engine on it. I have a great Johnson 150 that I want to put on it. Bayliner did not list a max at the time but rather what it came with at the time on a vinyl swatch which says 85 hp. I have a 1972 Larson...
Hi,
I need to remove the top/cap/shell off my 18' boat in order to redo deck/stringers/transom. What is the best procedure to do this. I understand you need to remove the rub rail and drill out the rivets. My problem is how to lift it off. I am working on this project outside in the...
Hi guys,
I need to remove my 1979 Johnson 150 from my boat in order to hoist the cap off. What is the best way to disconnect all wiring/linkage/tilt-trim lines. Any tips or tricks for easy disconnect/re-install. I believe power tilt and trim is hydraulic so what is the best way to purge/fill...
Hi guys,
Im starting a new project because I purchased a 1986 18' Ebb Tide Dyna-Trak SS with rotted stringers/floor/transom. The next step in this process is cap/shell/top removal (name varies by place). In order to do this i need to remove a huge 1979 150HP Johnson Outboard with power tilt...
I have a 1980 70 hp mercury thats having problems. At the begining of the season I replaced the board, wires and plugs and it was running great until now. Currently the idle is randomly rough almost like there is a misfire or a bog once and a while. The motor stalled on my 2x at idle last time...
Re: Steam? Exhaust? Normal?
Ripped down the power head and found a broken upper water tube grommet (hard plastic not rubber). Could this cause my steam issue?
1982 Mercury 70 hp. I have another thread but just wanted to get this clarified quickly. Last time i was on the water after 20 min of boating it stalled. I replaced a bad needle valve and the gaskets on the exhaust baffle. The other symptoms are on my other thread. But I just wanted to know...
I took apart the mainfolds on my 1982 Merc 70 hp and there is no thermostat in place. Before I go ahead and put it back together with 35$ worth of new gaskets, I want to be positive there is not supposed to be a thermostat in place. I have talked to a few people on here and have heard that mid...
I have been working on this fidgety engine for 3 months and counting and it seems like everything that will go wrong does. Its a 1982 Mercury 70 hp 3 cylinder with 2 carbs. I finally have good spark after replacing the trigger assembly and the board. The idle is adjusted a bit high because it...
Trying to figure out what gaskets to replace. The lower unit gear housing maintains a level of oil but the propeller slowly leaks out a light brown discharge which i am assuming is a mix of water and gear oil. What gaskets or O-rings or bushings separate the 2 and how easy are they to change.
The motor turns over and will idle for 5 mins and then stalls unless some throttle is applied. It sounds like its running on two cylinders also based on the rough idle...then it floods itself out because of all the gas that has built up in the cylinder. The trigger assembly had a corroded wire...
