First off, im not a Sunny owner, but my buddy has had two. A 28 and a 32. I've spent a lot of hours riding in and wrenching on both thru a lot of variations of both boats with him. But his 2001 Dominator (note - bare bones...no A/C heat, head, fridge or mcloud int.) with bone stock HO's would go 80+ almost everyday and when the moons aligned...82.xx. He also ran 28 bravo's stock. I know of several other HO boats in the same range. Also, I know other 385 boats in the 76+ range. Point is you are certainly missing a few MPH. I cant speculate as to where your loosing it without more info. Are you sure there stock 28 bravo's? What is limiting your top speed, just out of power or rev limiters? Compression check both motors. Is compression even across the board? How you are trimming the boat is certainly is a factor.

I'm looking for what I should be shooting for. I know that my MPH is down and looking at all possibilities in that. The drives are stock with stock 28p props in good condition, and was looking for those that have experience with the boat and set up to provide realistic point of where it should be so I know I'm in the ball park of having it right. I don't know if its ever been right. I have seen 78mph on GPS. Now it is pulling 72 and I'm standing on my head every night in this thing working on items. engines have 375 hr's.

all the what I am doing and what I need to do to regain proper MPH is posted in the do it yourselfer forum. Thanks.....looks like I'm shooting for 80mph which was my understanding, but wanted to hear reality from owners of boats. Of course who wants to post that real top speed is 78mph while its all over the place of the stars being aligned and adding 2 to 3 mph that their boat runs 85? I have compression checked one engine and doing the other one tonight. The starboard is between 162psi and 172 psi in the 8 cylinders.

bottom clean with no knicks? What about the props and skegs? Anything else dragging below the hull? That boat should run 80 all day long.

CATF800, sorry if I was not clean in my first post....yes you should be looking for 79-80 on normal days. I have ran on and with several Bone stock HO boats at those speeds. Those experiences are from participating in the annual Sunsation Rally a couple times (Awesome time BTW!) and recommend it for any Sunny owner!

I am actually surprised we have not had someone from the Sunsation factory chime in already with more info and help for you. If you havnt done so already you might want to post this question on the Sunsation websites forum.

Lastly, another thing you might want to check drive alignment. As in Toe in and Toe out which is set via your Tie bar. I believe its recommended to set them with a very very slight toe out but don't quote me.

My Dominator is an 05 with 496's not the HO's with labbed props seeing 78 with a really light load of fuel and 75 everyday. My buddy has had two different Dominators the first was an 03 with HO's about 80 everyday of the week and his most recent an 01 with 500 EFI's 88. Are you using the speedo or a GPS?

I had the outdrives removed this winter, gone through, engines aligned with outdrives, steering aligned, props checked, gimbals replaced, etc......

GPS speedo. one of the engines is not running up to snuff and having a hard time figuring this thing out.

CatF800 I believe we met the other day at the marina. I know you have the scanner for the engines so which engine is not running correctly? If you want to go for a ride together I might be able to help you out. Just let me know. I am going to try and go out tomorrow so maybe we can meet up then and go for a spin. You can PM me and we can chat more!!

Starboard engine runs 4600 rpm top speed and port runs 4900 rpm. all compression seems good between 155 to 172 in all 16 cylinders. Everything is clean on the bottom with props looking good and outdrives stock and cleaned. 32 wanted we can go for a ride this spring and check it out. i will be going through a lot of things this spring as well.
