    Troubleshooting 1999 Johnson 225 HO

    Okay, so... I have good spark on starboard side, all 3, nice and blue, jumping the gap no problem. Port side I have no spark on the middle plug (#4?), the other 2 are perfect. Plugs are a little black, except for the port side middle, that one looks brand new. Pulling the spark plug leads off...

    Troubleshooting 1999 Johnson 225 HO

    I'm guessing yes as the mechanic that did the work before I bought it diagnosed one of the problems as "no spark on some cylinders". He apparently fixed the spark issue though. I will check spark this week when I get back to the boat.

    Troubleshooting 1999 Johnson 225 HO

    A little update - Put the boat on the water again, no more overheat warning since putting in the new impeller. Disconnecting the temp sensors made no difference power-wise. Still no power, not enough to plane. Starboard cylinders are not running. Pulled the plugs and motor still ran the...

    Troubleshooting 1999 Johnson 225 HO

    I'll be launching the boat for the first time this year on Friday. Gonna disconnect the temp sensor and give it a shot. I'll have my bro-in-law at the motor with a temp gun to verify we're not overheating. By "pack" are you referring to the power pack? If so, that was one of the things the...

    Troubleshooting 1999 Johnson 225 HO

    Just a quick update - Over the winter I spoke to a few knowledgeable boat guys and the first thing all of them mentioned was the prop hub. Boat came with a Raker 14.5 x 24p. I sourced a Piranha prop 14.5 x 23p for cheap, will be launching the boat next week for the first time this season...

    Troubleshooting 1999 Johnson 225 HO

    No, oil tank wasn't present when I bought the boat. SLOW mode does sound like what I've been experiencing, now that you mentioned it, not being able to go over 2k rpm and all that. Hmmm... Would SLOW kick in because of the oil warning? The warning only beeps after about 10 minutes @WOT (2k...

    I'm gonna try tinkering with it myself, going with some of the suggestions here. Is there anything else I should be looking at?

    Troubleshooting 1999 Johnson 225 HO

    Think about all the fishing holes I can hit up on the way home from a 24 hour drive, with the boat to boot! Edit: I'm in the GTA, btw.

    Troubleshooting 1999 Johnson 225 HO

    Yeah, I added premix at 50:1. And yeah, seems like she's had some use and possible neglected. Would the vro pump cause these symptoms? If so, wouldn't pumping the bulb @ WOT provide at least *some* sort of improvement?

    Troubleshooting 1999 Johnson 225 HO

    I will definitely look into these things. I'm not sure actually, the alarm goes BEEP-BEEP-BEEP at about 1 second intervals. I did not install a new impeller. I just assumed it was something the shop would have done/checked when it was in there. Though I did order a new complete water pump kit...

    Troubleshooting 1999 Johnson 225 HO

    Hey guys, I have a '99 Johnson 225 HO with a problem that I'd like to figure out. Motor is on an '89 21 foot Stratos bass boat that I picked up about a month ago. Motor seemed to run fine on muffs. When put on the water it has next to no power (13 km/h @ 2k rpm WOT) and the boat does not...
