I repowered my 2016 Triton 20 TRX with the 4 stroke 250 Pro XS. Previous motor was the 2 stroke version running a ZLock manual jack plate with 10” setback at max height adjustment, motor mounted in center hole. and running a Fury4 25” pitch. I run power-poles and lithium batteries, lots of tackle, but fish alone predominantly.
The new 4 stroke was mounted in exactly the same position. Based on the YouTube videos interviews by Ken Smith with Mercury Racing I bought a Bravo 1 FS 24 pitch. When I test ran it I had too much stern lift and barely had to trim the motor to get on plan. But when I slowed down the bow came down and hooked badly. My question is if I raise the motor 1 hole will it have a significant enough impact to reduce the stern lift to balance the boat lift? The Bravo I maxed out at 5600 rpm and 66 mph. The temperature was in the 90s and water in the mid 80s.
I put a Fury 4 23 on and it runs 67 at 5780 rpm’s fully trimmed
looking for how to set up to run the Bravo or is it just a miss match. I liked the attributes of the Bravo on plane. Love a 4 blade for handling and stability. The Bravo seems like it has more potential speed if I can reduce the stern lift
Hi Marathon, I would definitely consider raising the engine up at least one hole if not two. The underside of the gear case provides a huge amount of stern lift in addition to the prop, the more you can get out of the water while retaining efficiency and handling, the better your boat will perform.
I am running a Bullet 21xrd with a 300R/sportmaster lower, Motor is mounted on a 15 inch setback fixed Jackplate set for 1 3/8 inches above the pad. Prop is a Max5 ST 31 pitch and I am running 95 mph fully tournament loaded with two guys. This is my second Max 5 because I lost the first one due to prop shaft breaking. Mercury replaced my prop and lower unit under Mercury warranty. My concern is: Both my first and second Max 5 has a fairly severe vibration momentary when coming out of the hole. Vibration goes away when up on plane, I did not have this vibration when running other props. What is causing this vibration? How can I eliminate it? Or is this OK and I shouldn't worry about it? I need your help, Please..
