Re: Jack Plate Adjustment Question
Sorry for the delay in responding back, went to WV for the holiday. Now, back to getting the boat ready for spring (or a calm winter day).<br /><br />Evin300, I'm putting a 50 HP 4-stroke Mariner onto a 17 ft. Lowe Roughneck (MT1760). I'm replacing a 25 HP Honda, which would push the boat at about 20 mph with the factory prop.<br /><br />I have not bought a proper prop yet, most people are telling me to go with an aluminum cupped 14 pitch 3-blade. (The motor has a 12 pitch prop which I'm pretty sure will overrev if I open it up and trim it out. Do you have a prop recommendation?<br /><br />I'll mostly be using the boat in long narrow tidal creeks (very smooth water), so I would like to have as steep of a pitch as possible. I don't know if the motor will do it, but I'm hoping for 32 - 34 mph on calm water and no wind in my face.<br /><br />Total normal weight for everything (boat, motor, gas, battery, tackle, me, passenger, etc.) is about 1,500 lbs. max.<br /><br />Got some questions on water pressure. What pressure range should I be looking for with this engine? where is the proper place to install the water pressure fitting?
