TONGA,
you out there ? I've got a question for you. I've got a '91 Merc 90hp ELPTO and it doesn't have a tach. I'd like to put a tach in so that I can experiment with some different prop pitches. I've found a good deal on a brand new one on ebay but I'm not so sure that it will work. It says that it'll work with all 12V six pole alternators. I also found another one that's similar but this one says that it's compatible with twelve to twenty pole alternators. I was going to call Merc today but got busy and forgot. Do you have any idea what type of alternator my Merc may have ? Unfortunately, the auction ends in about 90 minutes but there's anoter one running for about another six days. If it looks like it'll work, I'll bid on that one.

Thanks for any input !

John
