interesting question...

Here is my situation, and my thought pattern...looking to hear if I am ignorant, overly cautious, or right on...

I just went from a 1994 Bass Tracker Pro 17 with a 40hp Tracker motor that I mixed the oil and gas, to a nice Alumnaweld with a 1998 75hp Mercury that mixes the oil itself. Here is my thought pattern. If something was made by people, it can break. Would it be wise to eliminate the possibility of the oil of not mixing and burning up a motor, and go ahead and still mix 50:1? I was sitting here in my office here at church and a guy who works on my motors (retired boat mechanic and owner of a boat shop for 27 years) said that it mixes and pumps as long as the crankshaft is moving. But, I would hate for something to go wrong, and with something like this, when you found out the oil wasn't mixing for some reason, its too late.

Just your thoughts...I respect them!

Thanks,

You don't hear about the many, many thousands of those motors that are still out there running strong. Sure it can break and ruin your motor but as you said that applies to anything man made. Where would mankind be today if everyone thought that way. Don't take me wrong, I am not criticizing you, just trying to make a point. If it makes you feel better about it then go for it. But don't tell your wife you are going to replace the washing machine with a scrub board because the machine might spring a leak. (Sorry, couldn't resist). For the good news (if memory serves me) that motor is pretty easy to convert. Remove the oil tank and remove a gear on the end of the VRO. It will smoke a little more at low RPMs as it is use to burning a 100:1 mixture at idle.

Your motor has been mixing it and working right for 14 years.....must be a good system. And as Bill says there are a lot of them out there going strong.

I know some motors have an alarm on them if they aren't getting oil, or even shut off and won't start! Am I right in thinking this?

You are right they do have an alarm to let you know it is not mixing and an alarm to let you know when it gets hot. I have had this happen to an outboard and it was a total loss. But I have got another one now,I hope it doesn't happen again.
But what I want to tell you is,you can insure your whole boat,motor,and trailer for around 10 to 15 dollars a year. Its worth it.If you tear up one prop the insurance will have paid for itself. just my two cents

Who do you have your insurance through? That is cheap! And, the insurance would cover something like a burnt up motor due to mechanical issues?

My insurance is with farm bureau. Now I'm not sure if it would cover that though.

Any of the DFI motors are oil injected in some form or the other, there isn`t a two stroke motor made any more that isn`t unless you get into the very small outboards.. You don`t see a ton of them laying in scrap yards. Personally I would keep the oil injection system make sure the alarms are functioning properly.

Don't think Farm Bureau would cover mechanical issues. I'd carry some oil & make sure the alarm works.

I have been an insurance adjuster for 43 years. No insurance policy covers mechanical breakdown unless it is due to an exterior source, such as the infamous ice bag getting over the water intake. That has been a mechanic's favorite way to get claims paid for years. Most late model motors have computer diagnostic modules and can tell exactly what happened to an engine. That being said, I have a 1987 Mercury 150XRII that has oil injection and has never missed a beat. The warning alarm will go off if the engine is having oil or other problems. Run it like it was designed and you will be fine.

do you shop insurance often ? most seem to base premiums based on payout for the previous yr . If you let it ride "so will they" . boats, 4-wheelers , side-by-sides should be checked every yr . jmo .
