    Bringing an old Johnson back to life after sitting 10+ years

    Case closed. I didn't have my tubes lined up. When I split them again, the impeller pumped water on the muffs while rotating the drive shaft and water flowed through the powerhead from the pickup tube. Put the two back together and paid extra attention to the alignment. She pee's know and runs...

    Bringing an old Johnson back to life after sitting 10+ years

    That did the trick. Put in the new key and torqued down the flywheel nut to spec. Primed the fuel system and she fired right up without any trouble. Now on to the next trouble. Since I am on muffs, I only ran it until the heads were starting to get hot and only idled, but I wasn't getting...

    Bringing an old Johnson back to life after sitting 10+ years

    Um, yep, I knew the woodruff key was sheared before I even took the flywheel off. I was able to break the nut with my breaker bar and holding the flywheel with my other hand. Definitely NOT torqued down. Pulled the flywheel and confirmed. Looks like I'll be cleaning up the shaft and replacing...

    Bringing an old Johnson back to life after sitting 10+ years

    Well, the carbs weren't directly the problem. I took them both off and completely disassembled, cleaned, and rebuilt with another new kit. Adjusted the floats correctly and confirmed float needle operation. It's not pouring fuel out of the "breather" hole anymore. Unfortunately, I still have no...

    Bringing an old Johnson back to life after sitting 10+ years

    A couple of years ago I picked an old bass boat out of a farmers field as a project. Their nephew had parked it in 2009 and it hadn't been touched since. $100 for the titles and I got started. Engine is a 1987 V4 90hp (J90TLCUR). Pistons were shot. Instead of dealing with that, I just bought a...

    Need help designing new livewell system

    Thanks for the thoughts dingbat. Where does/should an Aft box drain to? Draining to the bilge just seems like a bad idea, but I only have one overboard thru-hull in the stern (which is for the bilge pump). I'm not opposed to putting in another one for the box if that is the generally accepted...

    Need help designing new livewell system

    I am restoring an early 1980's Cajun bass boat. The boat has a livewell at the bow and a livewell at the stern. When I got the project, it was only half way plumbed up so I don't know exactly how it was set up now how it SHOULD be set up. I have included a drawing with some explanation. There...

    Testing Power Tilt/Trim Off The Boat (Completely Disconnected)

    I am refreshing/rebuilding an 87 90hp Johnson. I just finished breaking down the midsection and now getting ready to check out and refresh the tilt/trim. It worked before taking the OB off the boat, but I need to give it a more thorough inspection. The outboard is completely disassembled...

    Screw on Side of Lower Unit - Purpose?

    This should be simple. In this image, what is the purpose of the screw circled in red? It's listed as a bearing setscrew but I can't tell what its full purpose is. Part number 324852 for a J90TLCUR, if that helps any.

    Inspecting Lower Unit For Problems

    I am currently restoring an old bass boat. It had been sitting in a field completely untouched for at least 4 years (and unknown how long, if any, before that). The outboard is an '87 90hp v4 crossflow (J90TLCUR). I am rebuilding the powerhead due to low compression in 2 out of 4 cylinders with...

    Here we go again... 1981 Cajun Bass Boat Complete Restoration

    All of the above first post occurred back in early July. We don't yet have a shop or garage out here so my work area is entirely outside. Down here in East Texas, it's just too hot during the summer to do much. From then to now, I just tinkered a bit here and there. First, I started to break...

    Here we go again... 1981 Cajun Bass Boat Complete Restoration

    I have been away from the boating scene for quite a while now as we were raising our kids, traveling the country, and enjoying life. With both kids about to be done with High School now, we left the big city to finally settle down. With that change, we lost (got rid of) the hustle-and-bustle and...

    1987 Johnson 90 - Block Rebuild Upgrade?

    Thanks guys. Good discussion on the upgrade possibility! It sounds like I'm probably best to just stick with a 90 block if/when I decide to give up on the current block. Sorry for the delay. I haven't much time to go out to the boat this past week. I went out today and snapped some pictures of...

    1987 Johnson 90 - Block Rebuild Upgrade?

    I picked up an '87 Johnson 90hp V4 that hadn't run in 4+ years (history of engine unknown) for nearly nothing. In doing my preliminary checks, I was getting low compression (90-94-94-95). For piece of mind, I'm going to get a rebuilt short block. I'm restoring the hull from the trailer wheels...

    Cranking outboard on the stand

    I’m getting ready to start another old bass boat restoration. Picked it for $100 out of some country folks land where it had sat for 4 years. Before I get overly invested, I need to make sure the engine is good. It is a 1987 Johnson 90 (VRO bypassed). It was clearly winterized before it was...
