First post and a noob to engines, so please bear with me.
We're currently looking at a boat that has a couple of 2006 DF150's.
Lightning fried at about 900 hrs and insurance rebuilt/replaced powerhead electronics in 2015.
Motors were run for 140 hrs, then the boat sat in a dealer's yard for a year or more.
I'm still waiting on the final oil analysis, but do have some diagnostics and findings that I could use some help interpreting.
Port engine compression
#1 - 216
#2 - 206
#3 - 215
#4 - 208
Starboard engine compression
#1 - 195
#2 - 205
#3 - 213
#4 - 221
Service manual states 14 psi max difference.
What does the 25 psi difference in starboard cylinders mean in layman's terms?
Other items noted were:
- Battery's had low voltage and wouldn't crank engines enough to start them. Both engines started OK with battery charger attached.
- Corroded tilt trim units on both engines.
- Water contamination and metal in port engine gearcase.
- Flywheels have surface rust and light corrosion was sighted on metal components on both powerheads.
- Engine cover latches are all stiff and one is broken.
- Electrical connections on both starter solenoids are discolored and appear to have been possibly overheated at some point.
- Other engine harness electrical connections checked for condition appeared clean and serviceable.
I really need some help to establish a fair market value for these engines to decide the best path forward.
After that I can decide if we'll rebuild/use them, sell/trade-in for new, or walk away entirely.
