Fuel Pump Repair Conversion Upgrade 1972 9.5 HP Johnson

[@nauticajr22]

I want to thank you for this awesome video. I just did this on my 20 hp 1972 johnson. I also could not find a bard that fit the threaded hole, but i was nervous about re-tappong the engine block so i used a die on the barb to size it down and it worked great. I took the boat out yesterday and it screamed! Thanks again!!!!

Thanks for your help with my 72 Johnson 9.5!

[@joeychilton6726]

Thanks for sharing! I refurbished 3 9.5s this year,and have wondered how to do that conversion.

i like to stand on the back of the zero turn T Mike 👍 handy for them small motor . I did the same conversion on my 72 25 hp Evinrude it’s been running great ever cents .

[@javed2547]

Good video gunna save some money on this one. Converting a force 85, hopefully it works!

Hey tmike, I've seen some comments that say 7/16 isn't the right size drill and tap. I'm just wondering what is the right size before I drill my engine to the wrong size

[@gustavolizarraga4322]

very good idea, I wonder how well does the pump deliver fuel on the engine at high speed? it can keep up with the demand? I just ask beacuse I did the arrangement, but with a fuel pump from a scooter, it looks smaller than the one you used, I must say, it works fine at low speed, but when I ask for more speed, it can't keep up with the fuel demand. got the same outboard, is a '71 9.5 evinrude. Thank for any comments.

I just did this on my 1972 Johnson 20 hp. I had no issues at high speed. This was an awesome idea!

[@gustavolizarraga4322]

@@nauticajr22 thanks You. Justo a few days after My first commentary, I got they same pump in the video, and works pretty good.

Great job thanks for sharing I have a question I have this motor it has stuck rings unit was stuck got it unstuck but compression is only 30do you have a video on this thanks

[@michaeljsimon]

Sorry I don’t do powerhead work - I recommend finding a used one on eBay - $150 to $250

[@fishtailfred8686]

Was there a reason that you did not also install an inline fuel filter? Cool video, the thought of there being aftermarket generic application fuel pumps just never occured to me.

[@Goomer]

Nice mod Mike.

I dropped the roll pin down in the engine compartment trying to install 0384597 Pinion Gear on a 1972 johnson 9.5 hp pull starter. How can I get it out?

[@michaeljsimon]

Turn da motor upside down and shake it - major drawback to those motors.

[@haroldpowell6860]

Thanks T Mike. I have two grandsons that can do it.

[@philb5]

Why would you drill and tap the hole when it appears to be already threaded?? Do they not make smaller threaded barb fittings.

[@nauticajr22]

I'd also like to know this. I have a 1972 20 hp. The thread is 5/16. I just ordered a 5/16 barb and the Kohler fuel pump. I'll let you know how it goes. Will be a few weeks until I splash it since I basically live in Antarctica (not really but close enough)

[@Blakethegoat]

@@nauticajr22did the 5/16 thread in?

[@johncarlberg4481]

Just strap some floaties on that mower and ya got ya self a boat

Best video yet, but I prefer your former sign off, rather than the dystopian music, Laissez Le Bon Ton Roulet. Oui Cher!

I have a 1965 6 HP Fisherman with a shot fuel pump. Can it be rebuilt/replaced or is there a Kohler model that I can retrofit? Thanks - your work is awesome!

[@williamboydfoto]

@@michaeljsimon - thanks! I assumed the '65 6hp and the '72 9.5hp would have different pumps.

[@williamboydfoto]

Many thanks! The conversion works like a charm!

[@tommyledbetter6211]

@@michaeljsimon this link doesn't seem to be working. Is it a different part number for a 1970 6hp Fisherman? Thanks

MAG1! I use their oil and grease. Great oil.

Hello T-Mike, I own a 1967 Johnson 9.5 ! Would this carbutor conversion work on my motor? It is a MQ-13 model.TIA!!!!!

[@joemilich]

Yo, T-Mike. How are you doing today?

[@michaeljsimon]

Another day in paradise.

[@evinrudej]

Probably gonna have to clean out that carb

[@michaeljsimon]

It was running rough because of fumes in the barrel. Ran great in open waters /
