My Suzuki engine has been completely serviced. When going about 4000rpm for about an hour and then docking for let us say 2 hours when I start the boat up again the revs will only go to about 2800rpm. If I then turn the engine off and then on again all is ok. We have done a complete diagnostic of the engine and everything has checked out ok. What the heck is wrong?

I have a brand new Suzuki DF225 outboard and it is less than 12 months into service on my boat and done 28 hours total. Its had its first service and has run very well and economically.
Lat week I was heading 8 miles off the coast of New Zealand intending to fish in deep water and about half way out the engine started to loose power. It kept the same revs but the engine note was different and I watched as the speed decreased and knots came down from 18 to 8-10. I originally thought it was the surge of the sea as we ploughed through the waves but it was not that. We then noticed the fuel consumption was very high so we decided to turn back and luckily got home.
When we experienced the problem I reduced revs and idled for 30 seconds and then took off again under normal power. The engine repeated this fault within 3-5 minutes and we repeated the process. We then stopped for half an hour and fished to give the engine a break but the problem persisted on continuing our journey back home.
Has anyone had similar problems?

I have a 2014 Suzuki DF50 with around 20hrs on it. Last trip out I noticed an intermittent squealing/sucking noise. It sounds like it's coming from the front of the engine, near where the motor cover sits. It didn't do it all the time and it did it in neutral and in gear.
It's like a loose belt on a car type of noise. Didn't seem to effect performance at all and I could sometimes get it to go away when idling in neutral if I gave it a few revs then backed off quickly. Not sure if it's there at higher RPM as the motor noise drowns it out. Any ideas?
Cheers,

Do I need to adjust the throttle vale sensor for the timing , I do not know the history on the motor I did do a compression test and I have 120 pounds in each cylinder thanks for any help
