It's called "pickling"...


The impeller could have failed for several reasons, Run dry, improperly installed, picked up a plastic bag, they never actually changed it etc....

Anyway, when the engine got hot and shut off, the steam collapsed and sucked water in through the exhaust... Silly common.

You need to inspect the exhaust hoses and flapper valves, get every single piece of the old impeller out, check the oil cooler and thermostat housing, everything, that rubber will be everywhere.

Clean it up, new gaskets, put it back together, it's likely fine... For comfort sake, have the heads mag checked my a machine shop...

Thanks for the info! Never experienced this before. Ive already taken all waterlines off and flushed everything. Unfortunately   we store the boat at our house in bullhead so i will be going back this weekend to sweat my balls off and remove the other head. definetly gonna have them checked and clean all the rust off the valves and ports. Ill post back when i get it put back together. hopefully all is good.
As for the impeller that was changed idk what they did cause I've never had one go out in two trips. usually last 2 years! we got hosed at that place anyways. Never going back.

Thanks. if i see it again ill look for the hin. Didn't even think about that.

What kind of exhaust? Maybe came up through the exhaust manifolds if they are logs. Happened to me before when I had the exhaust flappers go bad.

yes thats exactly what happened. not logs though. they are dana marine aluminum manifolds. I've never seen or heard of that until i talk to a few people that have experienced the same thing. good thing is after cleaning everything i think we will be ok with new gaskets and put it back together. no water in the oil or lifter valley. still gonna change it though.

You are saying it ran with that water in the engine?


No. Once i noticed it was hot i shut it down. when i went to start it after it cooled it wouldn't turn over so i pulled the plugs and then found the cylinders where full of water. I think we figured out what happened though. when it cooled down water came in through the exhaust filling the motor. never seen this happen before but i guess it does.

Got the heads off and my mind is boggled! All the cylinders where full of water. None of the gaskets looked bad or blown out in a spot. There is even rust on some of the intake runners. Not all only some. The exhaust manifolds where full of water also. It's like someone dumped a gallon of water in the motor. Does any one have an idea of how it would have got in and from where?

Took our advantage out last weekend and didn't even make it out of jack Smith before the thing pegged the temp gauge! Shredded impeller that was supposedly changed by a shop a couple months ago caused this. Didn't even last 2 trips!

Anyways on to my question. If there is water in the cylinders and it didn't ce!from the manifolds or a blown head gasket where else can it come from? This is a gen 5 BBC 502 crate motor by the way. Intake manifold gasket possibly?

I've got some of it apart. Gonna pull the heads in a little to see the gasket and check the cylinders.

Will this work on 175hp mercury black max


Sent from my iPhone using SoCal Jet Boats
Yes. You just have to get the right hub kit. i had it on a 150 merc for a while. gave the boat tons of bow lift. sold the boat so i don't need the prop anymore.

Just picked some stuff up from the local detail supply store. Probably could have used something rougher to start with. I still might go get some aggressive compound and try it out. Wet sanding definitely made the biggest difference.

This is my before and after, shine supply products, no sanding at all

I tried hitting it with some compounds first but it was just to far gone. Even with the wet sanding there is still some spots that are a little rough.

Finally got something done to the boat tonight. Wet sanded and buffed part of the bow to see how it would turn out. Not to bad considering how oxidized it was. Decided to just clean the boat up instead of re gel. Don't have the funds to drop a boat load of cash on new gel or paint. I'm jet boating on a budget! Or is that just normal jet boating
Other reason is I really like the design and colors that are on there now. I can live with some faded spots and stress cracks for now.
Some before and after pics.

I ended up buying a 19 from Johnny branch about a month ago. Been doing little things here and there so far. Stoked though and can't wait to get it running.

Welcome. This is a cool forum with lots of nice guys willing to help and not bash you. Fellow noon also. I just picked up a 19 myself. How fast does yours run and how much power you putting down. Trying to get an idea of how mine will do when I build the motor.

Do you plan to have new tanks built or source some that are close enough?

Sent from my Z981 using SoCal Jet Boats mobile app
Probably have them built. I want as much capacity as possible and fit the boat right.

Nice ride! I have a Spectra 19 with 1/4 stringers and floor.  Never felt unstable so far.  Then again I'm also not doing 80+ mph....YET.  Depends on the application and layup.  I ran 68 on gps in my old hawaiian and there was never and delamination.  I plan on keeping my boat these Spectra 19s handle great in my opinion and I think with full stringers would be a very solid hull at high speed.
Mineaswell do full stringers now while everything is out rather then building it and regretting it later.

Thanks. At this point I'm not shooting for insane speeds. If it will do high 60s or or 70 I'll bee happy. Maybe in the future when funds are a little better I might throw a blower on it which is why I'm building this engine as beefy as I can. I'm definitely going to start doing the inside now though. I started a build thread already on it. Just haven't had much time to work on it. I'll get back on it soon though.

If the tanks are good stick to ethanol free and/or AvGas. Ethanol and fiberglass tanks don't mix.

Sweet boat. Looking forward to following along.
They seem fine outside but idk inside. I really don't want to have to worry about it though. I just want to be able to pull up to any pump cali or az or wherever and fill up and go, so aluminum it is.
