Beachorbust Posted April 17, 2019 Report Share Posted April 17, 2019 So I have an opportunity to pick up a 16' sea nymph with an older mercury 135 on it for a song. This is overpowered. I am wondering if I can sell the 135 to a mechanic and buy a 75 or so in better shape and have it installed as an even swap. I know nothing about boat mechanics or the markets concerning outboard motors. I am just wondering if this is a possibility and what it would likely cost to get done. I would also appreciate the name of a shop, north of Boston that may be amenable to what I am trying to do here. Thank you. Link to comment Share on other sites More sharing options...
tyme2par4 Posted April 17, 2019 Report Share Posted April 17, 2019 (edited) How old is the 135? I've been looking for one to replace my 90hp Mercury 4 stroke. * Edited April 17, 2019 by TimS Buying, selling and trading is only allowed in the BST forum and never via PM Link to comment Share on other sites More sharing options...
makorider Posted April 17, 2019 Report Share Posted April 17, 2019 May as well leave it, I doubt you will come out ahead, particularly if you have to buy a harness, pay someone to hang it, etc Link to comment Share on other sites More sharing options...
salt deficient Posted April 18, 2019 Report Share Posted April 18, 2019 (edited) Leave it on there. You could probably do ok even with a 60 on it. I'd wouldn't be surprised if there wasn't much of a weight difference on it old vs new. I would also be surprised if the prop was right for it. Good chance you might need a faster prop on that boat... Only thing your saving is gas..... Also, during the outboard swap besides the harness, fuel fitting, shifter assembly/cables, you'll need to do maintenance on that too. fuel filter, water pump, plugs, carb cleaning, maybe even new fuel pump.

sams Posted April 18, 2019 Report Share Posted April 18, 2019 Check the boat for leaks. That is over powered by at least 50HP and probably more. If it didn't pull the transom off, it probably rattled most of the rivets loose. I sheared or loosened enough rivets out of a 16' starcraft with a 40 that I had to run the bilge pump every 5 - 10 minutes. sam Link to comment Share on other sites More sharing options...

Can't imagine someone wanting to swap a good motor for a not so good motor. Best bet is to find a good used one and pay for the swap then sell the bigger one on CL. You’re not some crazy uncle you know! I'm so glad I don't live in the fact-less bizarro world you live in...just sayin'. Link to comment Share on other sites More sharing options...
