The mercuryracing has the passport for the inboard racing engine, where they ajust the engine to the fuel.
Can't you use super unleaded? In Britain we have 99 Octane.

Looks good!

Looks good Janis! I am a bit jealous that you got more speed from your boat than our quad 300 But, the tubes are much smaller on your boat and the 350 verados are probaly more stable.

post more pictures and videos when possible.

Less horsepower/kg and more windresistance in the quad.

How do you link 3 engines with 2 throttles Petrov ? Have you just 'paired' 2 of them onto 1 throttle ?

Starboard and middle engine is on one throttle and when you coming up to some revs (dont know exact wich revs) the gear of the middle engine automaticly goes in, this is because it should be easier in harbours to only use the side engines.
