Short 2 pots.

A naturally aspirated V6 will be working hard to churn 350hp. When there's nothing left in her and you need to increase the compression to make the power it's probably time to just add another couple of cylinders. This thing won't have the torque curve of a V8 Yamaha or supercharged Verado.

You would probably have a heart attack if you ever needed to replace the props.

Bet it won't have to have the fly wheel changed at 200hrs like the Yamaha though..

I am intrigued as to the reason for the counter rotating props. Was it to reduce the strees on the drive shaft? Was it to reduce the stress on the engine mount? Was it to gain extra torque? The interest quickly wanes from there. Its not like they are going to sell a shit load here.

I have no comeback to that one..

The suzuki is measured with props and oil, dry weight is about 290kgs. The yammy is 365kgs, probably 390kgs wet. 60kgs difference. Also remember the suzuki is much narrower and can fit on the transom better.

Or worse still the gearbox. I have seen a few references to a dual prop counter rotating Yamaha as well (older motor) but can't say I have ever seen one in the flesh. Guess they will have the same advantages / disadvantages as the Volvo Penta system (not the forward facing one though)

the old two banger yamaha counter rotators in the states are meant to be good on hewes skiffs etc in shallow water. they recon you can run a lot shallower - use a jacking plate, trim up and run shallow. but in bigger hp it would be just more prop blade in the water so less slip i spose

[Chris Tucker]

Duo prop will be there for three main reasons.

1. Product separation (the other don't have it)
2. to offset the effect of the reduced low down torque when compared to the competition
3. It will eliminate the heeling moment generated by have one big prop putting 350HP into the water. Not an issue on big boats with twins. But if you're looking to put this engine as a single on a trailer-able 8ish m hardtop boat. removing that torque will make you far less dependant on trim tabs to keep the boat flat.

Preliminary pricing is really sharp. So similar to the Verado that it will come down to options and dealer discounts which makes it significantly cheaper than the Yamaha.

my Yamaha is 353KG full of oil?

HA HA HA

there are exceptions to that rule my engine has 1900 hours on the original flywheel
