Could this have been the problem?

I have been trying to figure out what is wrong with my ski for months. With no luck after changing the fuel lines, today i stumbled over this clear line (looks like the oil hose) that was packed solid full of sand, obviously clogged. I looked at it more and saw that the line went from somewhere underneath the exhaust pipe and was connected to the back of the hull. obviously it was a water line. went under the cooling section in a parts diagram and the same hose was found under the cooling system section.

Ski was starting and revving great out of the water, in the water it would idle great but under throttle it would bog and not accelerate. i wonder if this clogged hose is the culprit, and could i have created damage to the engine?
 
hose is number 11 that was clogged... what is it?

Yes...

That line is what drains your cylinders of water when the ski is pulled out onto the trailer.

My motor was doing the same thing. I usually clean all my lines out yearly but this line has a calibrated fitting on the back of the exhaust, that I couldn't get to. I didn't even think about it but my lines were clear. When I had the problem, pull the motor for a rebuild and actually posted here, in the forum. One of our senior members, "Dennis" was the one who answered my query.

Your problem is exact to mine. When I took my cylinders off, the pistons were a bit scratched up. He said that was because the water washed the lubrication off, causing metal to metal contact. I still had 135 to 140 PSI of compression.

You learn somthing new everyday in the forum.........:cheers:

very interesting. i wonder why the ski would run great for a few hours after i sea-foamed the carbs if this line was clogged... Probably switching to the dark side tomorrow and buying a new Honda aquatrax turbo...

I cant believe after changing all the fuel lines, cleaning the hell out of the carb, putting new fuel in the tank, that I missed this line that was 100% occluded by sand and rocks lol...
 
nope, took it out today and its still bogging and running like gargabe... whats the next step to try and figure it out
 
Nope...

im nervous to try it and ride the ski, was this 100% the problem? lol

No, I found out too, it was not the entire problem. There may be some issues with it but I dont' think it will greatly affect the engines operation.

First... The dark side? You've already dumped a lot of time, money and scraped knuckles to give up. No matter what you buy, at some point, you'll be working on it too.

You've done a few things to rectify your problem but I think we might start from the beginning. I have a feeling, it's in your carb. First, understand how this works. When your at idle, your fuel is coming from the low speed jet. When you start to speed up, your accelerator pump on the carb gives a squirt to start the acceleration phase. As you speed up, you go into transition where you have both the low speed and high speed jets contributing to the engines performance. Then, when you hit wide open throttle, your solely on the high speed jet.

If you changed your fuel lines because they were the grey Tempo lines and you did not clean out the carb, then you likely got some of the goo trapped inside the internal porting. Your micro mesh filter may be stopped up. Especially if your running kinda o.k. at lower rpm. When you speed up, you have to move more fuel through your circuit. If that filter is stopped up or partially blocked, then your not going to get the amount of fuel you need to run at higher rpms.

I have some info in "snipes korner" that might help you out a little on the carb. The link is down below in my signature.

How good are you with the carb rebuilds? Do you know how to take one apart. I'm going to shoot you a PM.......:cheers:
 
took off the carb and went through them very thoroughly, cleaned the hell outta them, and what do ya know. ski is running like a top... happy that my almost one year problem is now resolved
 
Dealership...

Just think, if you'd taken this to a dealer, they would have charged you $800 bucks saying your magneto was bad. Then, when you took it back on the water and had the same problem, they would have charged you $1200 bucks for your pump rebuild. Oh, about $3000 bucks later, they'd have figured out it was a dirty carb......

Being facetious.... I'm not a big believer in service centers at the dealerships.:cheers:
 
seriously, i would have spent more money then the ski was worth just to repair it... you'd think they'd go with the cheapest and easiest thing to fix first rather then bend you right over right away
