i have a 21 rev 4 coming. too cheap to pass up.
i run a 24trophy 5600 rpm mid 60's with a full load. 3.7ptp with wedges maxed on trim 8 ft roost. t
23 tempest ran a a bit slower loaded with more rpm 3.7 ptp
generally should rev 4go up or down? and like a lot or just minor adjustmenst. slidemaster adjustment on the water isnt easy.
trophy runs almost 68 just me. but very sensitive to height. 1/8th inch costs me 3-4 mph. trophy runs flatter not nose high.
