I may get around to this some day but it would be interesting to get RPM readings with a review of one of these outboards.
If I were going to purchase a tach now, it would probably be this one

B01E16UYFEI have not tried this one but what I like about it is that the pickup sensor includes a wire your wrap around the spark plug wire PLUS a ground wire. Some of those dont have a ground wire and I think having the ground would improve the signal to noise - more reliable readings.
The Suziki 2.5 is about perfect for the TI. Prop is matched well and it has a ref limiter plus four stroke. But.. you have to deal with changing the water impeller periodically and also never start the outboard without the impeller actually pumping water. Nice power for the weight.
Someone should also measure the RPM for the Honda 2.3. As far as I can tell (from this forum), no one has ever damaged this outboard from over reving with the stock prop but I understand that someone has damaged those really small two strokes. Sure would be useful to actually measure RPM as some have messed with the prop without actually knowing if they had a problem that needed to be solved.
The Honda is of course a great little outboard but about three weeks ago I was standing next to a sailboat with the 5 hp Suziki four stroke. About 100 foot away, there was another small sailboat that had the Honda 2.3 four stroke. Both were idling and we noticed that the Honda was louder even though we were standing right next to the Suziki. This was not the 2.5 Suziki but I would guess its similar to the 5 HP Suzuki (both water cooled).
But.. that centrifugal clutch and never having to worry about the water impeller even running the outboard on the hard sure would be nice.
FYI, here is a video of that tach in the link above.. Its in Russion.. LOL.. but close enough..
