Tigger:
That 80 hp Merc is a two-stroke and using it to troll at low speeds can foul the engine. To minimize this make absolutely sure you have the right gas/oil mix and that the plugs are clean and gapped correctly. It helps if occasionally you go out of gear and rev the engine to clear out the carbon.
As for speed, that 80 is somewhat high for that 15-foot hull and getting it to rev down to about 6-700 rpm will still drive the boat at top hull speed. One trick that’s been used is trail a five-gallon bucket behind the boat to slow it. There are plates that attach behind the prop and some like them but I’d rather go with a cheaper sea anchor such as the bucket.
However, even if it trolls a tad fast you can take advantage of that. Get your lines down to where you want them, go into forward gear until your lines rise a bit, then go to neutral letting the lines sink. Rinse and repeat. Lots do this because it makes the bait rise and fall – and that catches salmon.
If I can be of help with that engine give me a call at Brigantine Marine in Langley.
