Mariner 115hp 2 stroke weak tell tale and warning buzzer
Hi everyone I have been working on my friends rib sorting out a few faults and he has just had a different engine put on by a company in Southampton.
We sea trialed the boat today and we got a warning alarm, checked the tell tale and it was very weak and dissipated to almost nothing when engine was running at higher revs, we limped her back to the slip. There was no apparent blockages on the intake, so I'm wondering if the impeller is shot despite it coming from a company that has provided a warranty.
I'm reluctant to do any work on it as will void warranty.
What would people recommend to do in this situation as we are in Plymouth and the engine is from Southampton.
Thank you in advance,
