Kind of late to the party, but here goes.
If you want to make the most of your 60 HP there are three things you can do to it. Maybe five if you're feeling adventurous, but there is some missing info from the TXW's that I can't help you with unless you know how to measure angles properly:
- 15 pitch stainless prop (Vengeance) or 14 pitch Trophy Sport
- 6" hydraulic mini jack plate (TH Marine, Bob's Machine, Vance MFG, or SeaStar)
- SE400 Hydrofoil (Trackers usually seem to like them and respond very well to them)
- Transom wedges (to further decrease holeshot time)
- (optional) NGK BKR6EIX-11/ 3764 iridium spark plugs
The only caveat to transom wedges are that I do not know the angle of the Transom on the 175 TXW's. If they are similar to the Classic XL's then they have a 15 degree transom and to optimize the most out of the holeshot on these rigs, a 17 degree angle is more ideal meaning you would need 2 degree wedges.
Obviously this will cost you time and money to do, but if you have no intention on repowering then you may as well make the most of what you got, and these mods alone should give you a solid performer out of the 60 HP.
These mods combined should put you at an operating RPM of 5800-6000 RPM. The 60 HP makes it's full power at the prop shaft at 5800, so anything less is just robbing you of power. If you have any other questions, hit me up! ?
