Hope to get some help from you all. I am a beginner so bear with me. I would like to buy a used, or maybe new fishing boat 16-17' deep v for use in California lakes and reservoirs, maybe even in some bays in Ca on good days. I am trying to determine the proper motor HP for the boat I should get. I have seen a Tracker Pro Guide V16 (beam 88", max wt 1150#, transom 20") but it has a 40HP Merc 4 stroke. Boat max rating is 75HP. I have heard conflicting info about whether one should opt for the max engine size and avoid underpowering the boat. I am told the 40HP should push the boat 20-24 mph max on flat water. I don't really know if this is good enough for my applications. Any thoughs? I plan to troll medium size lakes in CA but occasionally go to San Luis or other larger reservoirs, Lake Tahoe maybe?
