I'm going install a mercmonitor in the next week or two and I'm replacing my speedo. I need some advice. Where and how should I disconnect my speedometer tube? Any pics? Thanks for the advice.

if you are gonna use dig speed theres a sensor on the power head that has to be connected to pickup on gear case

Pitot sensor is no longer standard equipment on this engine.

Simply disconnect the tube inside the cowling and plug it there.

Thanks. It's already clogged with wood anyways ;) What should I plug it with? Can I use anything or is there a merc number?

[EuropeanAM]

Anything you plug it with (that's water tight) would be acceptable.

You could also use Part# 859747 AND Part# 859732 (Both required).

Would these 2 same part numbers work to plug it off on a 2021 175 pro xs 4s?

[EuropeanAM]

Yes sir.
