Why would my boat pull to the right? It gets worse as speed increases. 140 evinrude will cable steering

Under the cavitation plate and above the prop is a little anode that acts as a rudder. It is used to counteract the torque of the turning prop. That needs adjusting.

Yea just read about steering cables snapping(scary stuff)
Will be going hydrolic as soon as possible.
The little anode is just to the left of centre how do I
Tell wich way to adjust( right or left) ? Or is it jist trial
And error.

If the boat pulls to the right (starboard) then adjust it a little so the back of the trim tab (fin)is more on the left hand (port) side. If the trim tab anode is severly corroded it won't be as effective. A little trial and error will sort it out.

Check the tilt as well?  Bow up/down makes my boat tend to go port/stbd (or the other way, I don't know, i just get confused these days)

Sorry to confuse the issue but I've been through this with my old boat and took me ages to sort it because I was going the wrong way at first.

The more I think about it the more I doubt my own advice. I may be telling you to turn it the wrong way

The tap thing mentioned above is mentioned in the evinrude/ johnson owners and books and servive repair manuals.
u will be surprised at how little adjustment makes such a big difference.

The hand book also mentions that the adjustment changes at different speeds...
So choose if u need to have the boat most straight at troll, cruise or WoT.
On our boat , adjusted to cruise it pulls, a little if idling in gear or trolling, and also less so at WoT

on the mariner i had,there was a set of grooves and the anode had groves,fin was in groove 3(to the right) from memory,steered straight.cable steering.
