also my speed oddomiter is not working rt , it works part time butt its not rt. when it does wk. any sugustoins.
if it's a pitot tube type system, look for mud and gunk plugging it up. ream it out, compressed air the clog out, however. don't know about how to repair the speedo if it's faulty. imho, scrap the speedo for some other useful gauge. my boat came w/o a speedo, a tach only. works good. since i was curious about my speed, a gps works great for a precise reading of speed. an analog speedo, pitot fed will give ya an idea of how fast, but they can be off pretty bad.
i know its no power steering havnt been able to look at unit yet
adg. you trim tab. if ya ain't got one, get one. my mc-1 drive from 75 has the long fin. it does do work and adjustments do make a difference in how it steers. fwiw, mine sits a little to starboard. it's set for no hands steering at 2500 rpm (happens to be 25 mph, gps), trim up one bar on my gauge, normal load of me and the ol'lady and a cooler full of pop, about 3/4 tank of fuel (12.5 gal of fuel, 3/4 tank). at this speed i steer straight and can let go of the wheel. any other speed, and it pulls a little one direction or the other.
