I'm picking up a Mercury 5hp 4 stroke long shaft for my 17' Lowe Deep V. Currently I'm using the 90hp Mercury 2 stroke for trolling and I hate it. I know big motors shouldn't be run like that. It does okay speed wise for salmonid trolling but for walleye, it just can't get down into the 1.0-1.5mph for running harnesses. Any suggestion on mounting this sucker? Any knowledge about this would be greatly appreciated as I know nothing about doing this. Thanks. Wanna kill these ads? We can help!
