Cal I think what Mike is saying is that he has heard of the 2190 going 58 pretty common but he cant get his over 56mph.
OK so for the 2190 and propping…Mike dropping your motor with no jackplate was a good move as you can tell by your results. Now I always have had a jackplate making it easier to dial in. I’ve had 3 2190’s all ran different speeds with my 2013 being the fastest by a few(3-4) mph. My 2 favorite props have been the Turbo 1 21p and the Pro Series 21p. Pretty similar props. I did run a 23p Pro Series on mine last year and was a couple mph faster but only turning 5500 and lost come control in rough water.
On my new 2016 I have tried a fully balanced and sharpened Tempest 21 and a Saltwater 20p. Tempest ran 55-5600 @55mph hole shot was so so. The saltwater ran 57-5800 @56.5. Much better hole shot as well.
I think over the years there has been some slight tweaking in the mold and they aren’t as fast as the 2013.
So for starters you need to be running a prop at 5700-6000. If once and a while with heavy loads and hot out you run 5600 no big deal. I will be curious to see what you get out of the 20.5 bravo. I think it will be great low and mid but no gains on top. I have a buddy that runs the 20p on his 2013 and he dropped a couple mph from his turbo 1 21p. Another buddy is running the 22p Bravo and seeing 55-5600@55 and another is running the 4 blade Yamaha and similar result to the bravo. Both of these boats are 2016.
For me I think I am going to try a turbo again, maybe even try a 19 tempest to see if it helps get some stern lift, then it might be off the custom shop haha. I saw my buddy has a 19p Enertia on his new 202 Lund GL with 300 Vrod.
I’ll keep you posted!
