Hello all! Im a newbie here searching for your input. I have an '03 TR185. It had a 150 XR6 that met its fate when the oil injection failed. She ran pretty good with the XR6, no jackplate and a Tempest Plus 23P. I could get to 60 (gps) at about 5800 rpm then she'd chine walk line crazy and eventually blow out the prop kicking the aft end of the boat to right and scare the poop out of me. Anyway, I located a wholesaler who did not have a replacement 150 but had a Merc 200 EFI. I don't fish tournaments out of this boat so I said what the heck. Also had a him ad a 6-inch JP for an additional 100 bucks. This motor, from what I've been told has the 2:1 gear ratio rather than the 1.87 or whatever on the XR6. My hope was to get close to 70 mph. Im still running the 23P and can reach 5800 rpm but only getting about 63 with the propshaft approximately 4-inches below the "pad" or v i this hulls case. I've only opened it up for short periods (10-15 secs.) due to having ran about a tank full with double oil. So, does it sound feasible to get 70 mph with this setup?
