I just picked up this SeaPro model 201 outboard with a small swim platform on the port side of the outboard. Problem is the current single step ladder on the platform is way to short for senior citizens like myself to use when boarding from the water. Been browsing multiple sites for a replacement telescoping platform ladder about 3-4 steps I can add back there. Seems none of the sites I have found give much information on installation and actual operation. I'm really concerned about vertical stability, don't want the ladder pushing/collapsing into the transom when trying to use it. Does anyone have experience or something they can recommend that would be a sturdy reliable ladder.
