I have a Bastracker boat with 1986 50hp 3 cyl. Mariner. I'm having problems with the tach. The range selector in the rear of the tach is set @2. The selector only has settings from #1 thru #4. Is #2 the correct setting?

Re: Tach settings

Laddies. The tachometer is made by Medallion Instruments. Is that your question? Thanks for the reply.

I don't use medallion but if its like teleflex it should be set on 4, hopefully someone that uses them will respond--Bob

Re: Tach settings

Will setting it to 4 do any harm?

I don't belive so it should be 12 pole or 6 pulse to run off the alternator if anything you would just get a low tach reading

Thats what I have now in the #2 position. At WOT the tach reads 3000-3100 rpm. I'll try the #4 in the A.M. Thanks for he help.

Re: Tach settings

Maybe a dumb question, but does it sound like it turning 3000 rpm at WOT? I wear a hearing aid but I can tell the rpm's pretty good by the way the motor hums without looking at the tach. Maybe your only doing 3000?<br /><br />Jerry

I'm no expext Jerry, but by the sound of the motor it's turning pretty high RPM's. Any troubleshooting tips I can try before I buy a new tach. Thanks for all the advice.

Re: Tach settings

When in doubt buy a tach and set it for the correct stator poles according to it's docs.<br /><br />Tachs are way cool in getting the rest of it all together properly. <br /><br />-W
