Fished a TX last Saturday. Boat started to hesitate on dead stops and kept bogging at high speed runs. Stopped and fished a few area's then around 1pm it just quit.

All it would to is crank and...

So my fishing and boating season has been pretty slow... got the boat out last Sunday with a new in line oil check valve. Smokes the same, no change so I guess it's time to replace the pulse fuel...

I'm having a hard time matching/locating my serial # (OB944770) from Don's site.

I'm sure most parts are interchangeable with other years/models but it helps me in figuring out what I'm looking...

Thanks, still have factory oilier installed...

I have the wmv carbs 16-1 3423, 16-2 3423, 16-3 3433.

I'm about at 2700ft above sea level, when Lee Sanderson installed the powerhead it might have been at 174 ft? I have never changed them or ...

I'm willing to paypal a few bucks for em'!

No. I assume I need to remove and test the stats on a pan of boiling water?

Made it back out this morning with the hose disconnected.

Started right up smoked as it usually does, let the boat idle while I parked the truck. It was not smoking as bad as it did in the past....

Went out last Sunday and left the hose unhooked at start-up all through the day. Seemed to run fine, smoked about normal at startup and did not seem as bad from spot to spot.

Heading back out...

From what I've been reading I believe my Thermal Air Valve is the culprit. If so that's a salty little bugger...

Heading back out Sunday and will see if leaving the hose unhooked will help.

Started up with the hose connected, ran down the lake fished for about 2 hours. Before the run back I removed the hose, started right up and did not smoke near as much. Got back to the ramp and...

and just so I know the alarm is a steady beep... beep... beep... beep ect correct?

Glad you're feeling better Don!

Found out the hard way (as usual) about the SCALDING HOT water. I could tell that the stats were working, from a trickle to a hard stream from the tell tail.

Any...

okay, got the pump and impeller replaced. All went pretty smooth and strait forward, that tube gave me a little trouble at first but it went back smooth after that.

Got it out in the driveway and...

Thanks for the explanation, it's been awhile and just don't want to mess anything up. I remember a friend doing his for the first time (years back, 70's merc), somehow the LU got stuck in forward....

so remove in forward and reinstall in forward, when reinstalling the prop should turn counter clock wise. I'm doing this one by myself this evening... just don't want to mess anything up trying to...

Shem says put it in forward gear when reinstalling.

Last time I did a water pump I'm pretty sure it was in natural uninstalling and reinstalling. How...

Thanks, Don, will pull the hose after engine has warmed up.

Been 3 years since the the pump was replaced, Sanerson Marine did the last one when the power head was replaced. Stats were replaced...

Took the hose off and tried to start at the ramp on the trailer. Tried for about 2 minutes and would not start just sputtered so I put the hose back on and it fired right up? Smoked like a crop...

Thanks for the reply JOE.

Might be a month before I'm back on the water, does either end need plugged or just leave it hanging?


143 huh... good to know!

It was 70+ on Friday so finally got a warm compression results.

Fallowed the directions as Don requested and below are the results:

105 110

108 110

108 110

So I finally got around to doing a cold compression check. Not sure I like the numbers.

PORT STRBRD
113 118

115 119

118 120

Assuming port is left and starboard...

Thanks! :thumb up2:

Just curious as to why air in the line would cause the excessive smoking. Or is this the first step to figuring out the root of the problem?

Thanks for the reply Don,

I had an issue last year where the main tank (REMOTE?) ran out of oil and the the top tank ran down to the alarm sounding.

Idled back to the ramp, oil was still up top...
