I think I need to replace #10 in the linked diagram.
Engine ID is 70973R
https://www.marineengine.com/parts/...manufacturer=Evinrude§ion=Intake+Manifold
However none of the sites I visit list it. Any assistance would be great.
Additional question we put boat in water and ran for a bit, at lower speeds it ran fin, at higher speeds it ran at the appropriate revs and then slowed, then back up, then slowed. Over and over. I'm thinking air in fuel lines messing with the mixture? Boat has been in cave storage for 5+years. Or could the broken gasket above cause the up/down/up/down? Boat runs fun with no cutouts or issues at low rpm/speed.
I did get the previous engine not turning over figured out after my last post. Bad terminal block in battery compartment, not grounding engine well enough, and a faulty black/yellow wire connection in the ignition. Bypassed the kill wire to a momentary switch until a new ignition switch gets here.
Thanks in advance!!
