Went out today with an experienced Ribnetter! Thx Paul. He kindly took a photo when when we were at about 4000rpm (attached). Cav plate is fully visible. Would love expert opinion as to whether we have it "right" now - about 1.5 inches above the bottom of the V. Thank you.
=============
Incidentally, it was a wonderful autumn day. We had a fantastic time. See photo of Bosham. Hard to believe it is 19th October....
Aim to be going out most weeks for rest of year on variable days of the week. If anyone wants a trip out in her please PM me. And.,...with reference to "another" thread - I won't be charging for fuel etc !!!
Wanted to post an update. Below stats are all 2 way runs averaged.
The new shorter leg engine and the new prop highrt pitch prop has moved me me from a splashy 6000 revs and 40.9 knots to a low splash 43.5 knots at 5700 revs. Former was with two blokes and 55L of fuel. Most recent is with 5 blokes and about 75L of fuel.
Needless to say I am well pleased. Thank you everyone for all your help.
She feels really secure at speed and comes out of the hole really well.
I can see the cav plate at speed. It is possible that I might try moving the engine up or down one hole later on in the year.
43.5 knotts is 50MPH, 5 up and half a tank of fuel, no cooling, cavitation or handling issues.......leave it alone.
Any tiny marginal improvement in any aspect of the boat's performance by moving the engine is going to be at the expense of something else.

It all sounds pretty much spot on...
I suggest if the OP isn't happy with those stats/performance ...His only real option is a Bigger more Powerfull Rig.
In the final analysis maybe the Thread would have been better headed as Suzuki 150 "RIGGING" challenges

So 50mph from the Suzuki 4S. I assume this is a 4cyl model, 2.8L 16v
What boat and length is it, and what speed "did" you get from the Opti? (There's 17 pages to trawl through)
We're going from the 175 Opti, (same engine) getting 53mph flat out, to the Merc 200 3.4L V6 [emoji15] Humber 6.3 OP
I'm running a Merc f150 on a 6.5 Coastine and that does 50mph two up with around 90ltrs on board and the acceleration is amazing.
I'd be surprised if you're not back here singing the praises of your new 200.
I'm confident it'll go a lot better than you're expecting, particularly hole shot.
Hope so! Being fitted back end of the month.
Biggest difference will be noise at idle. Can't see the hole shot or torque being better than the opti 2 stroke - but we will see. Hence I was curious about Bruce's comparison between 150s
An update. 7 of us (not small blokes) and full tank of fuel and we got her over 40kn average 2 way on a slight chop. Well chuffed! That's better than the 150 Opti!!!
She is the 6.5M Solent referred to in my signature. Suzi DF 150

Glad you got there in the end[emoji106]
