Could be the sensors on the risers. Any codes?
Have you tried ohming out the sensors for comparison.
There is a upgraded one.
This look like yours. (borrowed from another person diff site)
The discharge should be above the water line.
You sure they are bilge pump outlets beings there is another one on the other side
Does your hoses have a syphon breaker, with the vent fitted up high above the waterline?
Looking for paint other then the rattle can paint that volvo has for there outdrive.
More of a enamel or epoxy that will last on a drive kept in freshwater 6 months of the year.
A lot of topside paints available but you can't use them below the waterline
Trying to get some drive part numbers for ordering and can't access the info. All it does is give me an oil reservoir
This is the same issue i had when you revamped the site.
I can't even get through on the www.volvopentastore.com/Online-Store
or...
