Mercruiser Alpha One - Trim sensor adjustment with no Trim Gauge

[DaveBad]

I have a 1994 Bayliner Capri. I just finished replacing all the bellows and wanted to make sure the trim sensors were set right. I did put a scratch mark on them before I took them off and installed them as they were. All the info I've seen online references using the Trim gauge but I don't have one. Any input would be greatly appreciated. Dave

If you put marks on them you should be in the ballpark. Plenty of you tube videos out there to adjust your senders without a gauge.
are your senders in okay condition?

Senders we’re working fine when I took them off. So far I haven’t found a good video that didn’t reference the gauge. I’ll take another look. If you know of one please pass it along. Thanks for your reply.

From your description I’m thinking if your boat doesn’t have a trim gauge then you wouldn’t really have a need to have the gauge side sending unit adjusted correctly as there’s nothing to have set up properly against.

But the trim up limit switch side ought to be adjusted correctly to help with things like accidental over trim, lower the chance of U-joint damage, etc. all in which that needs to be adjusted to the trim cylinder pin to pin of 20 and three-quarter inch as noted below.
