I picked up my 380 yesterday. HP 500 EFI's XR's with ITS system, with new style whipples.

The changes were as follow's
1] Transom mount low water pick ups
2] New sea straners
3] Boost guages
4] 100 mph GPS [remove 80mph]
5] Hydromotive 5-blade [no 30]

Results: solid 12 MPH, from 81-82 to 93-94. The scream of the blowers is unreal. the acceleration from the torque of the whipples and the 5 blades is like night and day.

The trim tabs are simply not required to put the boat on plane.

The engines are running 5600 RPM. It is my opion that I need to go to no 31 prop's, so I will talk to Hydromotive next week.

Sounds Great! I know what you mean about the scream of the blowers, Mine start arround 3500 RPM.

What are you doing with the EFI Manifolds and intake stuff? I have two other engines I am planning on building and I am looking for a HP500EFI Setup. Are you willing to sell them?

Do you have any pictures?

Raypanic: I am planning on purchasing two World products marine marine motors for a 30' boat and want to use the EFI setups removed. If I change my mind I will call you.

I will take photo's of my boat in the next couple of days and post for your review.

Thanks Steve

Hey steve, how about those pictures? I am curious on how much room you have in the engine compartment. I am contemplating a spark plug change and am not looking forward to it. I do have a couple of spare engines I am getting the urge to rig them up with the newer whipples......

Glad to hear boat is doing good. Nothing like gettin on & being thown back when you hammer the thottles.

I agree on bigger prop.

Go easy on the takeoff's. The whipples build all kinds of torque at low RPM's & can put a hurt to the bravo drive. The drive is like a bucket full of water. The harder you launch,the faster the bucket gets turned. Sooner or latter the bucket will be empty. Question is not IF drive lets loose, but when?

I did post 3 of my boat pictures @ the Photo site.

There are not very clear, therefore I will post new pictures hopefully this weekend.

Thanks Steve

Steve, Nice pictures! Nice Boat! I am jealous. Love the chrome cmi's.

Sejman;
When I saw the pics of your boat, I thought I was looking at mine.
Yours is almost a bigger version of my boat, right down to the graphics on the deck.

Sejman - beautiful boat, did you buy that boat last year? It looks exactly like the poker run boat the factory campaigned last summer! right down to your bezels and engine room stickers. It was 500's, XR's and I believe, about one of the first boats Merc put the ITS on. That 38 had a write-up in PB on the ITS, only 2-3 mph as I recall. You coming down to the cincy poker run?

Wow

Your right, I thought it was my boat.

Tell me more about your boat. What Engine's, props, speed.
