1990 30 hp Ignition Question

Hello,

I hope someone can answer this. I have a 1990 30 hp Evinrude that year ago had a powerpack incorrectly installed resulting in damage to the power pack and a few other parts. The person who installed the power pack did not correctly air gap the part which caused it to wear down, then crack and get caught in fly wheel. When the flywheel jammed there was damage done to the throttle linkage, the mount plate was slightly bent and the idle stop was bent and several wire were pulled and stretched.

While looking for a new power pack, someone who used to work in the field told me to get rid of the UFI, and get a mag plate complete with sensors and charge coils from a 20 to 30 hp 1993 or 1994 and install the power pack on the side of the motor claiming that the UFI system used between 1990 and 1992 was "junk". Does that advice make any sense to anyone, or should I just get a new power pack and replace it?

Also, would anyone have any pictures of how the plates are supposed to be mounted without the flywheel of a similar motor? When the unit jammed, it twisted everything around, and I'm not 100% sure of how the mounting plate is supposed to sit.

Thank you for your reply Bill. 

I know what the existing mag plate looks like, and have a manual.

Was hoping someone here would be nice enough to answer the questions I asked.

 

Thanks,

 Evinrude does not condone the mixing and changing of parts unless approved in written service literature.  You as an individual are free to do so with your own outboard, but you then assume all the risks and liabilities should something happen such as property damage or someone becomes injured.

I'm aware of the risks and liabilities. It's a 23 year old motor, Evinrude's contractual responsibilites for it ended years ago lol.

Still didn't answer any of my questions, but thanks Bill.

Re: 1990 30 hp Ignition Question

To answer your question, it would be possible to utilize a non-UFI system.  Mounting bosses for power pack may be missing and you may need to hack your own wire harness.

 

Failure of the UFI ignition module was a known failure mode.  It was caused by thermal expansion of the encapsulant breaking solder joints within the module over time.  "Junk" is perhaps a bit harsh as there are a great number of motors that have been running with the UFI system for a long time.

Thanks ElderSparky,

I don't have the experience with UFI myself to call into question it's effectiveness. I was just quoting the opinion of a third party who called it "junk", and that anytime he got a motor into his shop that required replacing the powerpack, would convert it to an external. It did seem a bit odd that they went to the UFI in 90, and then back to the external powerpack in 93, I'm guessing due to the expansion problem you mentioned.

 

The mounting bosses are present, and from what I can see the wiring harness from a 93 should fit. both the 90 and 93 have the same crankcase (PN 435943). The motors are pretty much identical as far as I can tell, other than a couple of things (such as the UFI).  It seems to me that a mag plate from a 93 should be able to just be dropped in, and then bolt a powerpack to the mount on the side. I was just wondering if anybody within the community had heard any of the same issues, and if it was worth doing it, or just leave it as is? If there is a problem with the UFI, would I just be wasting money throwing a new powerpack under the flywheel or is 

 

There are sometimes manufacturing or design issues with motors that have been "hacked" by aftermarket communities to great success, by the same token are there are instances of hacks to solve mostly perceived problems.

 

Thanks for the reply Smiley Happy
