Folks, I just picked up a new to me Lowe 170 with a Johnson 25 on the back (Model #J25ELSSS). This boat has been modified with three batteries in the back and currently has about 3/4 tank of gas. I've put new plugs in it, added Stabil to the tank since it was sitting for a few weeks before we got it. The motor is tucked back to the transom in the closest hole (manual tilt) to help keep the nose down.
With two humans on board it'll spool up just fine and start to plane but it sounds like it's not reaching full RPM. Now, this is by ear only since the rpm gauge is inop. It shows @15 MPH pretty consistently on the dash, occasionally creeping up to maybe 16-17. If this is what it is, I'm fine with it. But it seems like it wants to rev more but just never gets there. Prop is stock.
Thoughts?
Thanks in advance!
