is it possible to change the engine oil through the dipstick with a pump like the previous verados?
You should contact Mercury about that flaking paint on your lower units; mine were the same and they replaced all 3 under warranty
Did you use anti seize on all the bolts for the thermostat, and alternator belt?
So what are your overall thoughts on the V8 now that you have had them a while?
good stuff. but you missed the struggle single handed putting LU back up. i was looking forward to seeing that solo. also may want to mention torque specs, some folks w/o experience may think tighter is better – not always the case! personal preference I use a paint pen dealer style. the dealer tech i copy
their practice and mark hours/date on therm, water sep, water pump
(outside of case) ,oil filter.thanks again!
Fabulous job. Well done.
What would you do to decrease the engine noise by 6 Db as my Verado V8 300hp did not pass the noise test here in Switzerland and the Swiss dealer does not want to tell me his trick unless I pay him a fortune 🙁
I was thinking to use special sound damping material from the automotive industry and put it under the top cover. But I read that most of the noise is from the low part… any clue or free space I could insert some noise damping material without altering ventilation?
Can you post a video on resetting the maintenance hrs on the gauges?
Bluewater great video. Do you have the part numbers for the two tools? Why is the paint coming off your motors? They look fairly new.
The belt removal tool is unnecessary. You also don’t need to unbolt anything other than the the alternator (what you called the motor). Once the 4 alternator bolts are off belt slips right off. Saves you $50 for that stupid useless piece of aluminum.
