    Johnson stops dead!

    As my note in post #6, electronic components can fail when get old and heats up. I have had the same issues with at least 3-4 engines (Mercurys 7.5 and 9.8Hp in this case if I do not remember wrong.). As a roll of tumb is that electronic components lifespan is shortened by half if the ambient...

    Johnson stops dead!

    What is the brand of the new power pack for 43 dollar!! Check if it is a Chines manufacturer. In my opinion keep away from Chines aftermarket parts. It is crap, buy a OEM, Sierra or CDI part and you will not be disappointed.

    Lower Unit Bearing Carrier Leaking

    If you can manage to remove the lock nut and the carrier without damage them..... yes it is worth it. Change the o-ring and put some liquid gasket such as Permatex form a gasket aviation no.3 or equal at the o-ring. I use this liquid gasket in many application on outboards.

As you mention you...

    125hp lower unit change

    A dual exhaust LU will fit and work if it is a Force LU. Later in 1995-96 they changed LU to a Mercury style.. 85Hp was built until 1989 and in 1990 it became 90 Hp with larger displacement. I think the 90Hp had 2 piece drive shaft, the 85Hp did not. Maybe jerryjerry can confirm if that is right.
