fly fishing the salt, and the use of motors

[jeepster]

i just picked up an 8' glasply dinghy for 50$ and im going to be fixing it up and outfitting it as a saltwater flyfishing boat. ive never flyfished the salt via boat but i have lakes with a boat... but whats different is this boat will have a motor... if i was to troll flies or spoons using the motor vs rowing, how would that affect the fishing? 

now obviously ive caught fish from a boat with motors running, but never close to shore, in the shallows, with lines alot closer to the boat.  im thinking im going to be doing alot of rowing, but would using a motor (for trolling) make a differance?  im not dumb enough to go out on the salt with out an engine, but using it to fish is something i havent done as far as fly fishing is concerned...

id love some $ aka your guys

if your worried about noise get a saltwater approved electric trolling motor. keep the oars in the boat, just in case...

I troll flies on the surface for silvers all the time. Water needs to be fairly flat, but it is by far the funnest way to catch silvers. Best place to drop the fly is about ten to fifteen feet back in the prop wash. The fish don't care about the motor running. I've hooked fish with 1 foot of leader in the water hooking up the downrigger.
