Thanks, K447.

When I tested the de-commissioned paddlewheel in a ski (today), it appeared to work alright. Not sure what I did wrong with my multi-meter test of the paddlewheel alone!

Thank you bspanovic, I will PM you.

I have a 2003 Polaris MSX140 whose speedo doesn't work. All other gauges appear OK and the ski is otherwise in good condition.

I have performed the test on the paddlewheel as set out on page...

Thank you, K447. I will check my starter solenoid, but as a guide, the Service Manual (page 7.7) says "Resistance should be 5 to 6 OHMS". According to Ohm's Law that equates to a theoretical...

Thank you, K447.

So far my research on the question of how much current the coil draws (i.e. passes through the start switching/wiring) has failed to throw up the answer.

As per my previous...

Thank you for your prompt response, K447 - and for adding your perspective on the relative risk of inadvertently pressing the start button with the engine running.

I will contemplate what you've...

It is a while since I have participated in - or visited - this Forum; however, I am currently readying a rebuilt MSX140 for use during the remainder of our (southern hemisphere) summer.

Following...

Thank you, K447. I did obvious visual checks during the rebuild and replaced the zip ties when I re-fitted the jet nozzle, but I may not have observed a crack, especially in the through-hull area,...

One thing I wanted to check while I've got the ski in the swimming pool is the bilge siphon system: now checked.

My test involved putting the two suction lines in a jug of water and observing...

Thank you for that insight, martincom. As you suggest, elevating the front of the trailer is a simple process.

Martincom, in our part of Australia we don't experience anything like the extreme cold that you do (we regard 40°F as 'cold'), but 'winterising' for periods of ski inactivity still makes sense down...

Thank you for your responses, K447 and martincom.

My interest in the MSX140 - and motivation to rebuild our family's ski, whose engine was damaged as a result of a severely pinched thermostat...

There are other posts on this Forum regarding aspects of an MSX140 rebuild which I’ve undertaken during the past Australian winter.

Having completed the rebuild – and given that our family’s usual...

Thank you, K447; I suspected that might be the case.

A while ago, I noted this modification http://www.greenhulk.net/forums/showthread.php?t=219824&p=2416619&viewfull=1#post2416619 (see post #3), which seemed like a worthwhile modification for the...

I agree, Mr. GP1800, but I'm trying to protect the ski from operators who aren't mechanically minded and especially in moments of mild panic engage the starter when the engine isn't stationary.

I would like to add a starter interlock - to prevent operation of the starter motor while the engine is running - on our two MSX140s.

I understand from this thread...

martincom, I recall reading a post (or posts) by K447 in another thread on this Forum addressing the issue which I believe you surmise was the cause of the damage to the flywheel/stator components of...

I meant to add that to further improve the seal between the sender body and the neck of the oil tank, I installed a thin O-ring (20.35mm x 1.78mm) between the outermost two molded rings in the sender...

Nice refurb, martincom!

My apologies for the quality of the photo below; this is a 'braces and belt' approach to keeping the MSX140 oil level sender in place and minimising the amount of oil in...

Thanks for your extra advice, K447 and Mr. GP1800.

Thank you for clarifying the joint which needs to be sealed, K447.

Having thought further about this, I am inclined to run with your suggestion to use 3M 4200; however, I find that it isn't...

Thank you for your responses, Mr. GP1800, martincom and K447.

All components have cleaned up nicely and fit as I believe they should. I was able to avoid damaging the critical joint interfaces in...

Referring to the attachment (noting red arrowed mating surfaces), can someone please advise the correct jointing compound to apply when reassembling the jet pump components other than the joint...

Thanks for explaining what happens with the excess oil, K447.

I've had no problems with engine starting without any throttle; it took a couple of seconds of cranking on the very first start, but...
