Thanks.. I was told that it needed Negative Trim. Wasn't sure. So I hold a straight edge to follow the bottom of the boat... Then I make sure the center of the nut to the prop shaft is center of string..... I can do that.. I am General Contractor. I work of Center lines. I can't mess that up!!!

I REALLY appreciate the advice!!

I am still really curious of speeds this boat is capable. I know not all boats will do the same.. But if I had an approximate point. I won't beat myself to death thinking something is not right!!

I have heard the 900-950Hp this boat should run 130+.. ?????

What do you think??

Do either of you have any pictures of your dash and interior. I am going to add some gauges and some gps speedos to the back head rest. I have quite the list but want to get some ideas. I looked at the OE website.. Not much infor there. I googled Ocean Express and got a few boats. Not a lot of Ideas. Most are diferent then mine. I will post a few pics tonight. Maybe the both of you can give me some Ideas.

Thanks:ernaehrung004:

I got the string thing down pretty easy... The question I have is I have two elevations I can go from. I have enclosed a pic.. which one should I use. The one is 1" higher then the other

Speed: 130 is possible depends on your motor RPMs. I would not worry about spending too much dollars until you get the boat wet. You have a totally new style dash which is different than most.

How many diferent times did they change the dash. I am not sold on it. I may have to add some angle bezzels. I think once I am running to scan the gauges acurately may not be that easy.,

I took a pic of the dash so you can see.. I like to have everything real clear. Especially at 100mph.. I sat in the seat and some gauges you actually have to tilt to see clearly..

Maybe its me but that is why i wanted to see some others.

Also let me know about he string thing and what area is that started from

Thanks

String thing: inline with the drive.

You have the newer dash panel. I was going to switch to that dash panel. You have 2x the room than the one I have. I would have put a gps in the lower section and trim indicators on the right side. rpm guages are the most important on the top.

Start with the lower then raise to try. You should get a video of how the boat rides. Remember that it is not a V-hull. Cats ride flatter. How does the boat get on plane. If your props are trimmed too high, the props will wash out in the turns.

The boat actually comes out like a ski boat is what my buddy told me. There was a guy who was looking to buy it before me and he took it out for a ride. He said it came out pretty nice. He said he couldn't find the right props for it... Just to take a test ride. ( I can play with that once I run it next time)
He said the carbs were messing up. Mostly because it sat so long... The marina I am getting it off of say they only used the boat "maybe" 8 hours in four years. They have a huge high and dry and only have off Monday's here and there.

Thanks I will let you know the out come.

Dennis sent me an email....

Get your boat first and run it for a while. Then you will know what you
need. Arneson's rarely need anything. An oil change should be about it
unless they are damaged from hitting something.

Motors? Hard to tell what shape they are in. Change oil and run them for as
long as you can.

A good speed in that boat is cursing around 80-85.


I was told that the boat was cruising at 90mph at 4000rpm's

What poker runs do you guys do north. We are going to 1000islands next year. I wanted to do a couple other then the ones we do here.

You ever get a chance come do "Rock The bay".... A lot of fun!!

Trim Indicators??? I don't have adjustable trim cylinders.

I wasn't cool with the oil pressure gauges are angled. 50lbs is realy clear. above that I have to look around alittle.
