I am curious as to others experience trolling with a Tiara in the Great Lakes (particularly Lake Erie).

I have a 29 Coronet with twin 6.0L Crusaders (375 HP each).

At idle with both engines I go about 3.5 knots.  I need to slow it down to 2.2 knots or so to effectually troll for walleye on Lake Erie.  

Is it OK to just idle with one engine (and keep the other engine in neutral)?  Any adverse effects in doing so? Will alternatively charge batteries at that low speed?

I am trying to avoid using trolling bags.  Others (with different boats) that the trolling rods themselves / other gear will help slow the boat down too.
