prop markings are not very visible but this boat has what I believe is a 15p prop three blade aluminum. Seems very underpitched for the engine and at nearly 4k rpm tops at barely over 26mph. I'm considering a 4 or 5 blade SS 21+ pitch prop. I pull skiiers sometimes but interested in power and top speed moreso. Any guidance on how high to go and still have enough grunt from the 5.7L to get it going? any experience with 4 and 5 blade on such a vessel? any input appreciated.
