Rummers Posted November 11, 2020 Share Posted November 11, 2020 Hey Raiders, Very rookie question coming up, I have just removed my old 30HP 2 stroke and installing a brand new 25HP 4 stroke to my tinny. The holes for the outboards didn’t align (as expected). My question is, do I have to weld the old holes? And is it okay to just drill new holes for the outboard? Do I need to have the plastic cover in there or can I just mount the motor to bare aluminium? any help, advice or a point in the right direction for install of this motor would be greatly appreciated.

noelm Posted November 11, 2020 Share Posted November 11, 2020 Looks like the transom has been patched up a bit, what sort of motor came off it, they haven't changed the mounting holes for years. Link to comment Share on other sites More sharing options...
noelm Posted November 11, 2020 Share Posted November 11, 2020 OH, and you need a plastic or Marine ply spacer on the transom. Link to comment Share on other sites More sharing options...

It was a mid 90s Yamaha 30hp. Holes definatly didnt line up though. thanks for your help. Appreciate it Link to comment Share on other sites More sharing options...

It’s a rough motor and doesn’t shift into reverse (in the head). but ran well enough. trade it for a motor install 😂 Link to comment Share on other sites More sharing options...
