Alpha 1 Gen 1 Trim Gauge Help
 

Hello all!! First time poster and I need some help. I searched the forum and couldn't fine what I was looking for so mabye you guys can help. I'm restoring a scarab and I want to upgrade my gauges and I see that for the trim guage I can select either a 10-90 ohm gauge or a 88-1 ohm guage. My question is which is correct for a AlphaOne Gen 1 drive? Thanks for your help.

I have the Mercruiser manuals for the drive and engines. Neither gives an ohms range...so I'd go by the application. ie. specify that it's for an Alpha 1.
Don't say gen 1, that confuses the issue.
There is Alpha 1, (yours), or Alpha 1 Gen 2.

I thought the prealpha/alpha andbravo pucks were all the same...maybe Im wrong, but if there all the same wouldnt the guages be the same too??

OMC trim gauge is backwards from merc .I forget which is which .When you order gauge specify merc. Mercs are all the same .

Thanks for the input guys I was going to order from cpperformance and there site doesn't ask which model I'm ordering for. I'm guessing my best bet would be to contact livorsi and see what they say. :ernaehrung004:
