I might have an extra set, I’ll have to look. They can be welded using 356. My cousin doesn’t like weldig them, but I’m older! All the CV corners I’ve sold are originals that have been repaired, I’ve never reproduced any. The parts I reproduced were in 535 Almag (marine aluminum alloy). But unless you live on the ocean, these original parts are fine with a polish and wax.

I’m just about to head out flying for a while, but I’ll check and see what I have. In the middle of completely rebuilding a CVX-17 bowcap that came to me in 4 pieces so I have to check on how that’s coming at the shop, too. The 17/metric bowcap was different than the other CVX caps so a repair was a must.

So I've finally got the boat together enough that I can use it. Went to test it and no spark

Will be looking into it. Hopefully it's an easy fix.

I've still got to put the windshield on and hook up the fuel gauge and bilge pump.

What you guys think?

Keep after it, sometimes it can take a little troubleshooting to get all the kinks worked out!

Ya forgot the swoosh .. LOL

Should be a fun little boat! Enjoy it.

So had to take a break from the boat while I built my house but I got that done in march and got the boat looked at by a mechanic since I had no time. They claimed it just needed new carb gaskets but I took it out last Friday and the motor still leaked fuel after about 2-3 minutes of running. I felt like it had to be a small crack or tear in the lines so I replaced all the fuel lines from fuel pump to carbs in the hopes that it was one of those lines as there were some sketchy looking areas on them.

I'm going to clean the fuel residue today and try to run the engine for a few minutes to see if it's still leaking but I did have 2 questions. 1) is it ok to run the engine on the hose for 10-15 minutes to get it warm? I have the 'earmuffs' but didn't know if those were good for longer than a few minutes. 2) can i leave the carb cover off while running it so I can get a better look at what could be leaking if there's still a leak?

Thanks! Hoping this is it for the engine. Only thing after this is to replace the fuel sender and the boat will be 100% functional finally!

I think some years of J / E had plastic carb float bowls. Maybe there leaking ?
I've run mine on hose / muff's for more then ten min.
I think you just don't want to rev motor or hold it at higher throttle settings on hose.

Are you referring to air intake / baffle box mounted to carbs ?
If so you should be OK .. again just don't rev motor or hold at high rpm's.

wpstarling · « **Reply #71 on:** June 24, 2020, 01:23:43 PM »

they might be plastic. I'll look at them and see but i've replaced gaskets on them twice, does the plastic warp or crack? If they are bad can i get metal ones/new plastic ones or would I need all new carbs?

I will leave it at lower RPM's just need it to run and see if it leaks after a few minutes. Yes I am referring to the baffle box. I'm used to older motorcycles where taking the airbox off causes lean issues and I definitely don't want that!

I'll give it a shot.

Hyperacme · « **Reply #72 on:** June 24, 2020, 02:38:06 PM »

I don't know any of the details about plastic bowls, but have heard of people replacing them, because of problems.
Yep .. Ya get a lean condition with out box. But just idling on hose for a few min. shouldn't hurt.

i'm one of the few people without a FB

I'll give it a look and see.

I also at some point need to replace the prop, it's an old aluminum and is pretty beat up. I'm not looking for absolute top speed but something that will be good for tubing/wakeboard/slalom and just cruising. Any suggestions?

Hyperacme · « **Reply #74 on:** June 24, 2020, 03:11:53 PM »

I think Dave's running a 22P Raker prop on his CVX16 / 115 HP Johnson.
Maybe less pitch if pulling ski / tubes.

If you want hole shot, do not get a Raker. One of my Rakers was purchased from someone who had difficulty getting up on plane. Rakers are for speed - high rake and little blade area. Look into what OMC has available for general all around use - Viper, SST, etc.

Thanks David. I'll take a look at them. I like fast but I just know my family and the way I use the boat, hole shot is more important than all out speed. Maybe once my boys are older I can go all out

So the 'fix' for the warped plastic bowls is to sand them smooth. So i took the bowls off, grabbed some 800 grit sand paper, some water, and my spark plug gap tool and proceeded to check the bowls. When i started with them i could easily slide the .004" metal between my glass table and the carb bowl in multiple areas. After sanding for a few minutes I no longer could do so. I then put the bowls back on and started it up and nothing leaked! However, I took the boat out after church yesterday and it ran pretty good for a while but had some hesitation in the mid-range RPM's until about 4k or so then it flew. Went to put the boat on the trailer and tilted the motor up and....leaking, again. After everything I'm seriously considering selling this motor and getting a different one. There are 2 90hp's that look decent in pictures (still have to see them in person) but I feel that might not be enough HP. What are the thoughts on that? Ideally I'd love to have a 115 or more but beggars can't be choosers

Almost all carbed outboards will leak gas when you tilt them up. Take a carb that is not on the motor, fill it with fuel and tilt it in the same direction as tilting the motor up for trailering and it will leak.

Yes i agree with that, but the amount that leaks is what concerns me. I'm not talking a little bit. It's enough that the shaft of the motor, which is white, is now greenish/grey. The whole thing. Just seems like it's leaking more than it should be, not to mention the mess it makes!

I honestly didn't check before tilting it if it was leaking so some of that fuel could have been there before i tilted it. i just didn't notice it until tilting since it started pouring out on my boat and then the shaft/mid-section once I tilted back down. Going all out the motor was fine but leaking fuel already caught fire once and i really don't want that with my family on the boat in the middle of a lake or river.
