If I know without a doubt the TDC mark on my 1994 Johnson 90hp v4 Crossflow flywheel is accurate because I checked it to make sure. Can I use the "Joe Reeves" method to verify timing on this motor? . I disconnected the cables. I opened it up to where the carburetors are fully open, the roller in...

Yes, good point! 😊

I have used that method with automotive engines, but I figured the piston stop tool would be more precise for this outboard that likely has less tolerance.

I made my own, but my distance between mark A and mark B is 5 inches. My TDC Mark on my flywheel and pointer line up just like they should. . My thinking is my DIY TDC Tool works fine since all we're trying to do is find two reference points in the #1 pistons up travel and down travel. Then...

Yep, time is limited. If you could though, if you find the solution to the issue, please post what you figured out. It makes it helpful for others with similar issues. Thanks

I tried searching for an electronic copy for my 1994 90hp Johnson. I never found one, and I didn't want to pay for a subscription one. I ended up buying a used physical one on eBay.

Are you saying the plugs had a gap of around 3/8? Or that you used an adjustable spark tester and the spark jumped the 3/8 gap on the spark tester?

With your motor off. Check the voltage at your battery terminals/posts with a multimeter. It should be around 12.8v. Then, with the motor running, check the voltage at the battery again with the multimeter. Is it reading 16v, or closer to 13v?

When my Suzuki was doing something similar, it wasn't getting enough fuel. Enough for running in the driveway, but not for sustained use under the load of pushing the boat. Mine was the primer bulb. I had the issue with two primer bulb hose setups. So I bought, I think, a Sierra Marine primer...

Thanks

The 7000 Faria Tach should be here Monday. I checked the current prop on the Johnson. It has a 13.25x17. My Suzuki has a 13.5x15. It has the same splines. I'll see where both props put me for RPMs at WOT and post back.

1994 Johnson 90hp v4 Crossflow. . The throttle Linkage has about 1/4 to 3/8 play. See video. It might be hard to see it, but the plastic outer piece that I'm pushing and pulling allows the inner piece to slide in and out about 1/4 to 3/8. . Is this normal? It makes quite a difference in idle...

Thanks for letting us know how you tested it and your results.

How about a girl with kaleidoscope eyes?

I have this in my cart: https://a.co/d/0b11TYAP

I need to get a tach. It felt like it never completely wound up. It ran really smooth, but it sounded like it still had more it could go. Not that it felt struggling at all, just that it still had more to give.

All good. Got up to about 33mph

I just finished watching a video on it, and my 90 just takes two of the same gasket.

Ha! 😆

For a 90hp V4 Crossflow the stock prop is a 3-blade aluminum prop with a 13-inch to 13-3/4-inch diameter and a 17-inch or 19-inch pitch. . The one I have now is 17 inch. Going to 15 inch on my 90hp V4 Crossflow would put less load on the engine, correct?
