picked a 1989 19ft regency boat today, all new interior, new carb, new tune up, engine is clean enough to eat off of it. has a bunch of reciepts that came with it from previous winterizing and maintainence. aside from that, it has a 351 ford and a cobra outdrive. i picked up this boat knowing it had this issue, but not sure what it might be. it goes into forward no problem whatsoever, but to put it from neutral to reverse...you have to really pull...like your playing tug o war. any ideas? the shift cable is red, and looks new...but that dont mean a whole lot ive been reading here and there. it also has through hull exhaust that i can deal with in the short term, but i can see it becoming a nuisance to other boaters as it is pretty loud. is there a muffler that clamps on the exterior of the pipes...on the back of the boat? looking for a "simple" fix really. dont have to be dead quiet, but at least toned down a hair.
