Did you mean a boost hose? Air intake coming off the turbo?

Post your fuel burn numbers at cruise range rpm’s and WOT rpm.

Do you have data of “X speed at X rpm” ? – both historic and now?

Post some good pictures of your engines, the installation and the exhaust.

BTW, not following your format of Day 7, Day 1, today ..

I mean the hose that comes off the bottom of the intercooler that powers the turbo.

My boat has been very consistent since the day I launched it….
2500 RPM
25 GPH (12.5 GPH each engine)
25 Knots (SOG)

Right now, at 2500 for each engine, I am seeing 14.5 GPH for the port engine and 12.8 for the starboard engine but the port engine is not settling in (keeps hunting around 2500 +/- 30 RPM) so the starboard numbers are suspect.

As for the format…. Day -7 was last weekend return to home port Day -1 was yesterday and today was today.

I’ll report back on once I replace the fuel filters on the port engine and check all the hose clamps and clean the airsep. I will grab some pics too.

Thx
