Vintage 57' Evinrude 7.5 High-Speed quitting...

[frustratedboater]

Thanks all.. HighTrim- I appreciate your detailed explanation on the install. I din't exactly follow that, but I do remember trying to expand the seal into the grove so I wouldn't loose the length. I'll give it another peak and correct any flaws that may have happened.

Thanks a ton everyone...

Another thing I do that helps is dry fit it. Ensure the shift rod screw hole is lined up BEFORE you cover everything in sticky sealant and then try to do it!

Will do.... Back to the pressure tank, I did get the kit and sealed everything up and added some pressure from my air compressor through the connector on the air/gas line and checked for and leaks. It kept air nicely and is sealed up!

All the gaskets were in stock 'marine engine .com' and should be coming soon. I'l' be sure to post the results in a week(s) to come.

Well done again. Would be good to pressure test the lower unit. Not much pressure, maybe 10-15 lbs. Test in water to try and spot leaks.

ed. hand pump or foot pump works.

 

[frustratedboater]

That is a great idea. I always thought I needed a special tool...

 

[oldboat1]

yeah, find my little foot pump works (use it to inflate bumpers). Just never got around to getting a "real" pump.

 

[HighTrim]

For years I used a bike pump, with a gauge on it. I cut off the end of the hose that connects to the bike tire barb, then put on an end from a lower unit oil fill pump.

Pump up to 6 to 8 lbs. Submerge in water, turn shafts, shift etc.... and look for bubbles.

 

[oldboat1]

good point ^^. my little foot pump has a gauge. Think the last time I did it, I used the inflation needle through a little piece of rubber gasket material (held it in place by hand). End from a l.u. fill pump would be good (above) -- or maybe taking one of the drain screws into the hardware store, and finding a plastic match (drill it to fit the needle).

Just for grins, went on Ebay and see the Stevens pumps go for upwards of $130.

Those oil fill pumps usually have a cheap little clip holding on a clear tube... That is a great idea coupling it with a bike pump gauge. It's much better testing it before install than finding oil dripping.., and in my case, having to lift off the powerhead to detach the shift rod...!

High Trim, is that 'tool' patterned yet?

Good stuff...Good stuff!

Last night I saw my son checking out all the parts for the motor all organized and laid out on my bench in the basement and he starting to assemble, like a puzzle, and I had a flashback from when I was young. I was watching him play with stuff and making the sound effects of the pistons going up and down... "Hey, this goes here", and "does this go like that?" I did the same thing about that age and had the best time. It was exciting to see that.

Moments later he moved his way the the bottom half and was twisting the throttle and "snap" my tiller shaft snapped from the screw and the handle came off. BIG bummer!! He knew I was upset and ran off.

I'll have to talk to him later and let him know there are still parts out there for that...

 

[oldboat1]

delicate time with your son. I had something similar with a first computer I had brought home -- son changed settings, and I didn't know enough to reset them. Think I must have properly held my temper, because he still jumps in hands on as he should, and is now an expert 20 years later. (I went back to old outboards.)

I love working on motors with my boys. When they were about 5, I quickly learned that they needed their OWN motors to tool with.

I got them a couple cheap little 3hp motors, couple little stands. I loosened all the bolts and screws, and made them up a little tool kit. So they can take bolts out and put them back in. They actually like to clean up my motors. Whenever I get a new one, I give them a spray bottle, and a rag and let them go to town.

The reason for their OWN motor, was I had just finished a resto, and was in another room when I heard banging. Went into the shop, to see them with a couple small hammers wailing away on my brand new paint job!

So, they quickly got their own motors to work on. Keep me sane.

 

[frustratedboater]

Wow.. I don't blame you!

I've inherited my uncles evinrude yachtwin, little 3hp, and is half taken apart. He told me that his dad, my grandfather, gave that to "the boys" when he was real young and he had it on a little skiff growing up. That motor has been around the family, but I never saw it. A few years ago he passed it on to me knowing that I really love fixing motors and restoring them. Just knowing the history of it really means the world to me, especially, knowing its' history. I can't wait to restore it completely. It is a real special motor, one that I'll never part with for now... But I have had thoughts of returning it to my uncle, fully restored just to surprise him!

Looking for a couple of pieces for the cowl of an original Javelin. I need the rear Javelin cover that fits in cowl and the plastic insignia that attaches the the pull start cover. Any suggestions. Thanks Walt

 

[frustratedboater]

I personally, do not have and resources for your Javelin, but, perhaps, anyone here..?

I actually need a rear latch for this 57' Evinrude 7.5 hp... Anyone have a spare?
