Fixing issues in order of importance

[Johndhii]

I have an 89 Evinrude motor E150STLCEM, and was given a quote on issues with it, I would like to know which order I should do them in as cost is an issue. Mind you, I have put a top end on cost and want to do it so that I know that what I am doing will impact my decision to keep the boat at that cap and finish it, or cut my losses.
The issues I have been told are:
1. Propeller shaft is bent
2. MOtor mounts need replacing
3. Carburetors need replacing and the linkage is not right.
4 kill switch is bad

What order should I go about fixing these, preferably in order of importance. I appreciate any help I can get

Re: Fixing issues in order of importance

There are more knowlegable fellows here,now with that said. I would start with compression test,If the engine is bad no need to go further unless you want to decarbon or rebuild ,If OK the bent prop i would remove it and see if it is bent,I would next check the motor mounts than carbs,and before getting on the water the kill switch.
Did a reputable shop give this quote? I find it hard to believe a bent prop shaft without damage to the lower?

Re: Fixing issues in order of importance

It was a reputable shop, and they said that it was due to the stainless prop. I did see what they meant by wobble, it is slight, maybe a quarter inch but still there. The motor mounts are loose, will they cause the motor to fall off, or do more damage to the steering? What I am trying to figure out is what I can do myself, that I will see the benefits of to decide if I should keep going. The compression test showed consistent 105 +/- 3 and the motor would run, just not well

SS prop did not cause a bent prop shaft and a quarter of an inch runout is HUGE. I would get the prop shaft straightened 1st, but you check it with the prop removed and use a dial indicator to measure the runout. A decent machine shop can straighten it for way less than a new prop shaft. Continued running with a bent prop shaft can damage expensive stuff in the gearcase.

Not sure what you mean by 'motor mounts'. Mounting bracket? Rubber mounts? ??

Why do the carbs need replacing? They're usually just rebuilt with kits.

What do you mean by 'kill switch'? 0393132 EMERGENCY IGNITION CUT OFF SWITCH ASSY.??

What were you quoted for the repairs and was it broken down functionally?

Look at the BRP Evinrude website ... they have complete parts breakdowns and prices for parts on line.

Re: Fixing issues in order of importance

I appreciate all the help you guys are offering. To answer your questions,
The prop has play up and down, I almost think it could be bearings.
The upper and lower motor mounts, the rubber with the bolts through them.
The carbs actually need rebuilding.
And yes that is the switch I need that takes the lanyard.

I was quoted 5100 dollars and it was rough running and wouldnt start the last time I took it out.

Re: Fixing issues in order of importance

Look for a new mechanic. If you intend to fix only the most serious problem and attempt to run the engine, that would be a huge mistake. You need to fix everything before operating it. Failure to fix the carbs will cause a potential lean condition which can destroy the engine. Not fixing the prop shaft can destroy the lower unit. Not fixing the mounts can cause steering to lock. A non-functional kill switch can -- well -- kill you. Fix them all -- it is essential.

Re: Fixing issues in order of importance

$5100 is ridiculous for those repairs. The most challenging repair is replacing the rubber mounts if the motor has ever seen saltwater. I would believe `$800 to 1000 plus parts for all the repairs, assuming labor @ $80 to 90/hr. Parts are in the order of $200 or so. You get the idea ... find another 'mechanic'. Could possibly be a little more,depending on how much the machine shop gets for straightening the prop shaft. I would remove the prop and see how much lateral movement there is in the prop shaft ... you can not tell with the prop on, especially if it's not tight, the thrust washer is missing, etc. A few thousandths is OK. perhaps up to five thousandths. But again, remove the prop 1st.
