Hi, just tested the trigger on my miss-firing / down on power 60HP Mercury two stroke.
These are the readings
Brown and White/ Black = 0.816k OHMS
White and White/Black = 0.536k OHMS
Violet and White/Black = 1.206k OHMS
The figures in the repair manual for my motor are on the table below...
Can you take a stator off a Merc 75HP 2 stroke (which has a different type of switchbox design) and fit it straight onto a 60HP with its original switchbox?
I guess the question is, should stators and their corresponding design switch boxes be used together, rather than mixing types?
This is...
I've just changed manifolds and risers as a precaution (Dry Joint variant on 4.3MPI) - they were the original factory Mercury ones from 2005. So nearly 20 years of mixed salt and fresh water. The manifolds looked fine (other than flakes of rust inside) - but elbows were in a bad way. I'd say...
Hey all!
I have a healthy 2005 4.3 MPI, fully serviced etc that runs great. We normally boat on water that has a temperature of around 60F and have zero issues, boat sits at 160 all day long.
Question is - we’re taking the boat on vacation and the area we’re visiting has water temp of 77F...
Thanks, yes it was a little lazy on the stock 21p, the 19p Solas is much better, I value holeshot over top end and rarely run WOT other than planing out with a skier or heavy load. She planed out with 10 people and 3 dogs onboard recently, I was really surprised.
I’ll check the max RPM next...
Great to hear, that’s what I was hoping for. I changed from 21p (aluminium) to 19p (stainless Solas) based on the analogue tachometer reading a bit lower - be interesting to see what is really occurring!
Finally found it wedged down the back of the motor. Thanks all for the tips, I nearly gave up but found it.
All installed and working, no faults showing (other than the usual ones for items not fitted like steering angle sensor etc) - apart from the below?
Thanks for the advice, probably didn’t help on reflection that I was working at sub zero temps / ice on the floor so I guess bellow flexibility was at an all time low. Will check the others over carefully.
I just watched this on YouTube - the blue loom you see isn’t what I have on my boat (and looks like it may have the required plug) - wonder if the early MPI’s needed a different harness conversion? 🤷🏼♂️
