    Compression testing of PowerHead on Bench?

    Am I able to spin my 115 powerhead on my workbench safely, to test compression? Once my rings arrive, I'll finish putting this together. I usually mount it up to the rest of the leg (but all that is outside in the cold) to properly test. I thought if I just put the starter and selenoid on, I...

    do the 150 crossflows (1985) have a diff steering setup from v4's?

    Ive got a pair of 1985 150's recently and just beginning to mess with them a bit. I need to swap in a TNT motor to lower one so I can get it onto a stand to run it. But I noticed each of these has steering Tilt tubes, that are blocked inside, meaning they appear that neither had a steering...

    Please update with resolutions or update open threads-help others.

    I hope I'm not mis-speaking here!...And I don't mean to offend If I do. But Nothing is more frustrating (well I guess there really is now that I think about it), than to follow a thread that some very kind people have helped on...only to find it open and never resolved or even updated! The OP...

    SOLVED: Kill circuit not working on 1985 150. Is my diagnostic steps correct?

    Ive read the related threads on these not turning off with the switch, or direct grounding of of the Yellow/black kill line. I have all the switch and Remote/cable pin-out diagrams and am familiar with what line does what. In testing my new to me 150 on a stand, with remote and wired-up key...

    Purchased 2 complete 1985 150's for 400.00

    I'm so cheap, hate spending money.. I have several older v4 crossflows, but have been looking for a buildable v6. Finally a local guy was selling 2. Both are pretty clean, 1 was a freshwater motor, other Salt. He ran one, when the TNT motor went, he found a complete 2nd motor supposedly running...

    Am I charging? Mixed results with swapped Regulator

    Got a 1984 PHead on '93 Lower...Had an issue with Tach Jumping, and weak batterys..originally Volt meter and fishfinder would show up to 16v when Tach was jumping, and 12.5v solid when tach sat short periods at Zero--this was on the water and only above 3k rpm. So, did my research.....Found I...

    Are VRO and VRO2 pumps interchangeable between years if Mixing?

    Here's why I ask....Had a fuel delivery problem on 1984 115 (rebuilt Powerhead). It would come to plane, then die out. A couple seconds at idle and I could plane again for 15seconds.........I know it was fuel, So I swapped the VRO and did a complete carb rebuild. Test run ran real good...

    Bent floats cause this symptom?

    I put this motor together...Machined 1984 block, new pistons/rings/bearings etc...Been running great. Until last trip. For the issue, just tonight I swapped the VRO/Fuel pump unit with another (I mix), and did a complete carb rebuild properly( Berrymans, wire and air). Will test tomorrow. THE...

    Decarb during Rebuild break in period?

    I Rebuilt a block I had previously taken apart and stored. Its a 1984 Johnson 115 PowerHead on a 1993 mid/Lower. Hey, it got me back fishing. Actually the rebuild went nicely, I had all new parts and a new piston/ring set. Eventually I'll do the original 1993. I'm doubling the oil, and...

    Driveshaft binding up crank on v4?

    I know there are threads on this type thing, but since the upgrade it appears theres only an overall search, not in each section. Here Goes! My 1993 115 blew up...So happens, I had a 1984 Powerhead measured, machined & Ready to put together. It came out nice. This is temporary until my other is...

    Is this a crack in Rod cap?

    Hope pic posts, havent had luck with pics lately. Was reusing my rods and caps on a rebuild, and noticed this line. It was dark so I lightly sanded it so I could see it better. Not sure if its a crack, or what? I can just barely feel it with my fingernail. But the others sure dont look like this.

    Harness compatibility? 1993 115 to 1984 115.

    While my current block is bieng re-worked(1993 115)....I have a real itch to be on the water and fishing. I'm landlocked! I have a good powerhead, 1984 115 flatback, that was already dissassembled, cleaned and rebuilt sitting idle(bored, new pistons and rings) ready to go. I have verified its...

    Block compatibility? 115 crossflow

    I see these post around but still really dont have a definitive. The PN's are different So i guess the answer is NO. Here's what I'm facing. My running 1993 broke a ring. I took it apart. My machine shop said holes are not in spec and not round. I do have a 1989 90 block, and a 1984 115...

    Power steering causing a stall?

    Helping out a friend with his 2003 EFI 5.0 with Alph Gen2....Finally got it running and cooling ok. Was idling great on hose. We never gave it any throttle just idle and idle rpm seemed fine. We decided to turn the wheel to test the Steering, and rpms dropped and it died. Started up and tries...

    opinions on Cylinder condition. Repost, trying photobucket link vs pics

    Link at bottom to photobucket pic.... 1993 115. Took apart on bench after a problem. Starboard upper piston broke outter ring. I will dig into underlying causes eventually. Surprising there is little damage, didnt see any until I took out the piston. The walls are fine, no lines that can catch...

    I've read similar threads others posted with similar odd noises from the warning horn, bad horns, wiring, grounds etc.....Didnt quite see my whole symptom. 1993 Johnson 115. Last trip out above 3k, I hear 'Crackling" from the remote warning horn. I know my motor very well. I immediately took...
