Thermostat access?

[Glsjr40]

Can the thermostats be accessed on 1978 Evinrude 85hp without pulling the power head?

How does the fuel pump work?

[boats.net]

Yes can get thermostats out as long as no bolts break off in cover, then may have to pull powerhead to repair broken bolts.

the only way to get the thermostats back in properly though is to drop the lower engine cowling. its a pig of a job on an olderengine as most bolts will break.

the fuel pump works on the pulse from the crankcase.
pulse comes in and moves diaphragm back and forth then fuel is sucked in and pumped out.

very simple very basic easy to service and very reliable.
boats.net carry plenty of spares.
