Propping an X-190 for Mid 50s with the Merc 4-stroke would likely leave you with a poor holeshot under a heavy load. You need a 21" prop to get to 56 MPH at 5800 RPM and a very generous 7% slip. That's using the merc calculator and the 1.92 gear ratio for the 150 Merc. That's a pretty big wheel on a heavily loaded DeepV with a 150.
I wouldn't ignore Brad's comments as I am quite sure he runs a glass DeepV with the power being discussed.
If Mid 40s are acceptable you could run a 17 and get out of the hole with any load I bet.
No. The Merc 4 stroke 150 is actually the perfect motor for that ride IF the owner is happy with a max speed of 52 or so full load. The hole shot is not only acceptable, it's great at that top end and proper tach reading. Overall performance with that engine is really really good.
The boat was designed to carry a full load with a 150, and it'll power with a 115 nicely. The 90 is not enough. 54 MPH with the 150, and you are looking for a boat that cruises at the 'sweet spot' in the low 40's. The X190 is not a big deep v, it's a hybrid high performance hull. Originally, it maxed out at 175, and Tuffy made the changes retooling it to meet requirements at 200, and the hull design is radically different than the 690 Ranger.
If top end is important, and you want performance and actually cleaner burning than the 4 strokes, go with a 175 Opti. GREAT motor, certainly not 'smoky' ( that's just not true at all). I owned an X190 with the 150, and one with a 175 Opti. I liked them both, but really liked the 175 best because I DO want to go faster. Hole shot was identical.
This is not a deep v walleye boat, gents, it's closer to a bass hull in lift and design, but it's a bass hull that will run the big stuff well with a multi-species interior. If we were talking 1890? Different ball game. |
