Johnson 1965 9.5hp MQ11C

[Trc118]

I just recently purchased this outboard, and while doing a water bucket test I noticed no water coming from exhaust so I shut it down. Shouldn't water come out the exhaust right away even if the thermostat isn't open? assuming I need a water pump rebuild kit. The sites I've looked at online don't go back Beyond 1968 for parts and manuals. any suggestions where to find? I'm also wondering if the 1968 mq14d or e would be the same? assuming the e references electric start? Thanks in advance.

Yes, it should discharge water any time it is running. Running in a bucket probably isn't deep enough. No, "e" does not mean electric start. They never made an electric start 9.5hp.

For the most part, your '65 and the '68 are the same. A significant change was made to the vibration dampening system. But water pump should be the same

Thanks F_R,

The water intake was submerged in a deep bucket for sure. Looking for the 65 or 68 pump parts now at various sites. Any recommendations for best price but not lacking quality? I'm a divorced Father of 5 with 3 boys still at home who all love to fish for their Dinner!

Water has to be 6" above the pump.

I put in barrel and stil no flow. I pulled lower and found pump impeller to look like attached. Now looking for best place to order pump rebuild kit. While pulling apart I noticed a bit of sealer where the pump housing meets the plate and where the upper and lower are joined together. Didn't think was nessesary, and if so, what would you recommend? General marine sealer or a silicone?

 

[racerone]

That impeller should have pumped some water.----It does need to be replaced.

 

[Trc118]

Yeah I thought it would have to and will replace. Need to find and order parts and install. Thiughts on my sealer question?

you can get parts for the motor at BRP dealers evrywhere or here on IBOATS visit LEROY'S ramblings site for a god article on the 9.5

I have one and it runs great

make sure you have the impeller key in place to grab and turn the impeller !!!

with the LU out look up the innards to see if the water tube is snug in the powerhead



push some water up the tube with a hose ...water should come out !!! if not water passages are plugged with something in the powerhead


maybe old impeller chunks ….:-(

 

[Trc118]

Thanks crosbyman! No ramblings only good knowledge there thanks. Drive pin was there, key wasn't blown out, and I will check the passageways. About my sealer question? Do you use and what kind of sealer between pump wear plate to lower end where mounts? Also do you seal where lower meets upper before you bolt together? When son and I tore down there was a thin bit of silicone in both places. Thanks in advance.

 

[Crosbyman]

cant say about sealers… I never used any personally I doubt sealers on the WP is the issue here

if you are worried about it just smear a light coat of silicone or gasket sealer on the lower joint and around the WP cover

with the LU out dunk it in a bucket and spin the drive shaft with a drill clockwise to see if water gushes out of the wp

if not there is something wrong with the wp


did you try sending hose water up the water tube ?? did the water come out the top ??

btw if you look closely on the wp upper half there is a tiny hole at the base ….make sure it is clear and open

see pic make sure you have all parts in yellow and check hole near arrow point

Great idea Crosbyman! Thanks for the parts picture. Did u get that on line? Waiting to see if I get this working good enought to spend money on manual. Part exploded digrams are probably all I need till fimiliar with motor. Where are these available on line for my old 1965? After I saw that I looked at my picture and see that my vanes are contured the wrong way for a clockwise shaft rotation and opposite the picture. Guy before me may have installed upside down?

 

[Crosbyman]

vanes will reorient themselves clockwise ...Don't worry about it


btw look at the site in yellow in Leroy,s MQ page just before the parag REMOVING FLYWHEEL


that site will give all you need parts wise just drill down to 196x then select hp motor size for exploded views and parts
