Quicksilver generator parts - Maxum Boat Owners Club

HavaMax · 11-15-2014, 03:04 PM

I am in desperate need of a couple quicksilver generator parts!!! Hoping the brain trust here can help save me some $$. I have the part numbers converted over to current generac part numbers. I am looking for Generac 70915-exhaust flange and 70917-Exhaust outlet. These two parts are mated together with cheap pipe nipple that has rusted thru and ruined the threads in each piece!! Cant believe it was actually designed this way?!?! Any way, these two pieces are over a solid boat buck!!!! I am hoping some retailer of supply house is willing to get these parts off of their shelf cheaper. I can just see these parts on some shelf somewhere with an inch of dust on them, just waiting for me to give them a good home on the cheap......

Now as everybody knows that if these parts made my maxum cooler, faster, and generally better than my dock mates I am the first to dig into my wallet. I am also a stickler for maintaince and keeping things in top shape......but these prices are crazy!!! So what say thee....give it to me straight I can take it!!

Max sorry cannot help with new parts. Can the old parts be re threaded or have a insert installed. You may want to have a machine shop look at them to see if they can be repaired

Mm.....I'm gonna check into repairing the threads...it looks like I will have to try to remove one end of the heat exchanger as I can not get the pipe nipple out of that side...[emoji35][emoji35] I hate repairs resulting from a very poor design!!! What do the salt water guys do with this horrible design!?!?!?

Just found I have this same problem. You ever find a reasonable solution?

We're used to replacing everything all the time anyway, so I doubt we'd notice.

But the reason for this thread is the expense of these obsolete parts.
I just crawled behind my 5.0 and found the exhaust tube laying on the deck, disconnected from the rubber hose and rusted off the heat exchanger flange. I haven't looked to see if the flange is salvageable, but the tube has two lengthwise cracks, so it's junk. I have an idea to make my own to replace it, but should probably make sure the engine runs first...

I was able to reuse the exhaust flange and outlet. I was able to remove the rusted pipe nipple and chase the threads. I didn't remove the heat exchanger, I used a brass pipe nipple. I had to cut the nipple in half, use each end and then slid high temp exhaust hose over the two halfs. Then used a wide exhaust clamp to hold it all together....sounds terrible, but actually came together very well....

True, however I was replying to the question asked at the time.

You happen to remember the size of the pipe threads, off hand..?

HavaMax · 06-02-2016, 07:48 PM

I believe it was 1 1/2"....I was able to get the old pieces of the pipe nipple out and a local machine shop had a 1 1/2" tap to chase the threads...

Thanks. I'm thinking about getting that size pipe and then welding a larger one over it that matches the rubber hose and then weld a bung onto that outer jacket for the water fitting.
