Here's one for ya' ! I owned a 25' Robalo CC in the early eighties. I chartered this boat in both fresh & saltwater for ten + seasons.
Looked up my records & averaged about 40 trips a year since I had other jobs .
This rig carried twin 150 HP Merc in line six's.
The average trip was 8hrs all troll rotating engines or on rough days using both !
Saltwater would run another set of trips in primarily fall , tuna troll chink etc.
So at 40 trips per season as the average lets say I put 5hrs a day on engines x 40 days as average that's 200 per year at the very least .
Times ten or so years that's about 2000 hrs in a very conservative estimate !
These engines never had a major , routine maintenance only !
No major break downs even on canyon runs !
I don't want to say it but I honestly believe there might have been as much as three thousand hours on those engines no way of knowing for sure
Guy bought boat & ran it in salt another 4 seasons w/o issue till he sold boat!
Lost tract after that!!
