Which hour/RPM meter for a new Merc 20 HP?

I ordered a new Merc 20 HP four stroke outboard, and I'm looking for suggestions on a hour meter, ideally one that reads RPM too.

My dirtbike has one, and I've come to appreciate it a lot. Pic below.

The new outboard is a 2 cylinder, tiller model, with power tilt & electric start.

Are there any "preferred" brands/models for an hour meter? I don't want an unreliable one. I do want a small and simple one.

I have one for my 1994 Johnson 50/35 jet similar to what you have on your dirtbike. Got it from Amazon. There are a bunch of different ones on there but I picked the one with the best reviews. Has been working great for the 2-3 years it's been on my boat. I even added about 6' of wire to it so I could extend it and mount it up next to my control box. No issues so far.

I picked up one from Hardline on Amazon. Works great. I think it was about $20.

I have a Hardline one as well but it doesn't show RPM's accurately, usually about 2x's what the OEM does, but I bought it for the hour meter, not the tach.

I don't have a Hardline, but with mine you need to mess with the settings to set it to the appropriate spark fire rate for the engine it is on.

Off topic but I gotta ask. Does your username come from that very famous Chicago area beer of the same name?

Tried every setting possible, hours online looking for solution, said THWI as the primary purpose is hour meter. I run the big motor at idle during the summer trolling for crappie, so the need for hour meter.

The screen name came from a reference to the bombs the Air Force was dropping in Afghanistan years back. I worked at an aerospace company then, and whenever we had an ugly problem it was common for someone to say, "Eh, just drop a daisycutter on it".

I started using the phrase outside work, then my moto buddies picked up on it, and it became my name. So I use it as a screen name too.
