Well, all the unethical Farmers, by illegally burning Purple gas in their cars and trucks for personal use, were not paying their fair share of Taxes

The cowl and face plate place it in the 74-75 era

Is the manual Valve on the Transom Bracket fully closed?

Back in the day, I remember Gasoline often was dyed Red, sometimes Purple. Though Purple was supposed to be used in Farm Equipment, as it wasn't taxed. Every Rural town had Inspectors with Tennessee Credit Cards getting samples from cars/trucks parked, Liquor Stores were a popular location. If...

Thanks for the clarification, when you said "OEM" in your original Post, I thought you were referring to BRP or Mercury.

Kind of like pulling the fuse used by the Airbags, cause you never use them

What tests did they run, EEG, EKG, Xray/CAT/MRI, Bloodwork(red-white counts, oxygenation, Enzymes indicating Heart Attack)?

Thank You for clarifying the Brand of the Oil. An inquiry to Sierra about the Oil, may have saved you some frustration. As a preteen(late 60s), I remember my Uncle using an Esso(Exxon in US) Outboard Motor Oil that was amber

Mercury/Quicksilver DFI oils, and some of Amsoil 2 stroke oils, are yellow/amber Myself I wouldn't use a DFI Oil in an Outboard that premixes the Oil with the Gas, as DFI Oils are not formulated to mix easily with gas.

Non-critical Sensor fault, however... Connecting a scanner to the Engine Diagnostic Port, is what needs to be done. Meanwhile, try checking for Low Gear Oil level, Water in Fuel Filter.

Perhaps the wire has a broken conductor hidden by the Insulation.

Planing speed is not something that is really all that adjustable, as it is determined by Physics, Hull design, as well as weight and distribution of. The more load in the boat, the higher the speed a clean Plane is achieved. You can force the Bow down at slower speeds by putting Trim Tabs on...

Yank all that Electronic Crap off, replace it with a Carb, and Mechanical Advance Distributor, if you want to have many years of trouble free boating. But if there ever is a Problem, much much easier to figure out what is wrong, and fix

Who did the previous Service? If you have documents that state that they only put 1.5 liters of Oil in the Case, and then sent the boat on it's way, you do have case of Negligence on their part, and that they should be paying for the Repair/Replacement,

It will certainly reduce the amount of Air that the Larger Primaries of the Squarebore could flow, and that could certainly screw up the calibration of the opening of the Secondaries. The Mercruiser Adapter I showed in post #11, did allow the flow from the Primaries to access the Secondary Side...

I have found power steering pumps can make a variety of sounds when they are being starved of Fluid

Since both cylinders are not firing, and the odds of both sets of Reeds failing is not likely, and it appearing that Fuel is not getting to either cylinder, maybe the crankcase isn't fully closed. I think it is time to pull the Powerhead off and tear it apart and inspect. But before doing that...

Edelbrock's adapter is one of the Worst. Chokes the larger Primaries severely The Mercruiser adapter, allows the higher flow from the Primaries to divert to the Secondaries inlets Yes, it is a 4175, the Double Pumper versions of the Spreadbores are 4165s. I had replaced the Holley 2 barrel...

Compression in the Combustion Chamber, yes, but to me, the Crankcase/reeds are suspect, as the OP has sprayed fuel into the carbs, and it appears not to have made it to the Combustion Chamber to fire

I have used a Holly Marine 650cfm Spreadbore Carb #0-80552 If you go the Edelbrock route, get the Genuine Mercruiser Adapter, while not the Best, it is far better than many after market ones
