Speed
 

I want to go faster. My Sea Ray 200 BR Signature Select -95 only makes 44 mph. I have tested some props:

Mirage Plus 19 - 47 mph (4400rpm)
Mirage Plus 17 - 47 mph (4700rpm)
High Five 19 - 46 mph (4600rpm)
My prop 21 - 44 mph (4400rpm)

What prop should I have???

Motor 350 Magnum MPI (290 hp), Bravo 1.
Dry Weight: 3300 lbs.
The boat is bottompainted.

I thougt this boat shold go faster!!!!

What can I do to go faster?????

Please help me:confused:

hmm that sound pretty low. I had a 205 glastron witha 260 hp 350. It liked the 21 hi5 . It did 57ish on gps. I would get a gps and dbl check the speeds and then look to the motor for weaknesses. You are triming it up propery??

We had it in the shop and they didn´t find any thing wrong with the engine.
How can I know that I trimming it right???

I appreciate all help I can get:)

I would expect your boat to run in the mid fifties. Look at your drive leg , it will have the gearing stamped on it near the ser#. If you have 1:50 gears a 21 " prop should be right and the rpm should be about 46-4800. At top speed your trim gauge should be between 1/4 and 1/3 of the way from the bottom. Get the boat up to top speed and slowly bring the trim up , when the prop starts to blow out due to being to trimed too high the boat will slow down and over rev.
hope this helps sj

Hi Manils,
what kind of mph. Nautical miles? If yes so you are in the mid fifty us miles. It's a little bit tricky because in Europe we use nautical miles(knots) or km/h

start with getting rid of the bottom paint. althought thats probably not all your problem.

I can rev 4800-4900 before the prop starts to blow out and starts to slow down. But the speed will not get higher only 44-45 mph.
I have not used a GPS only check the tachometer.
It shows mph not knots ( i have imported the boat from the states)

When I drive the boat it feels like "it is glued to the surface".
:confused:

hmm sure sounds like its not lifting the bow when you trim it. But you say you are trimming it till it blows???? Im stuck. Youre not running at high altitude are you?

I´m not sure about the altitude, but i have the boat in a lake in southern Sweden.

Did you check your gearing.... the reason I asked about alt.. is the higher you go the less power you make. Your prob is a stumper for me.

Can´t check the gearing beacuse of the bottom paint. :mad:

The altitude is 465 ft.

I think that the prop I have is the origanal prop (Quicksilver I think????)

well the alt isnt a prob then. your drive leg is painted??? Are you sure the prop you are using is a 21? If your gearing is 1:50 ... a 21 " prop should be about right. If you are geared higher than that ie 195 , you may need a higher pitch.

Move as much weight rearward as possible. Store heavier items in the rear storage compartments. Store only lightweight items in the nose.

I agree that you should see over 50 mph, but have a friend with a 250hp Mercruiser in a 202 Crownline that runs only 49, and I know his boat is lighter thna yours...

The prop I´m using is marked 48-16318-21. Do anyone know the brand???

According to the serialnumber the gearing should be 1:50

Hmmmmmm sorry buddy Im out of good ideas. sj

I bet the bottom paint is slowing you at least 3-5 miles per hour, it's common to lose 2 mph by just waxing the bottom, here is an easy way to tell if your trimed for max speed if the spray from your hull is only coming from the rear 1/4 of your boat thats perfect, if its in the middle or towards your bow you need more trim to get the hull out of the water

When the boat is in the water it "leans" over to the starboard side a lot, about 3,9 inches. Should it be so????

When a drive the boat the spray from the water is coming most from the starboard side.

Maybe your boat isn't slow as u think. Maybe just your gauge is slow. I would double check with a GPS.

slow boat
 

Hi the lean should not slow you that bad but can be real anoying are bolth your batterys on the same side and an ancher also? My Wellcraft came with the batterys on the driver's side and it leaned real bad with just me in the boat, so I moved them to the other side. I even got .9 on the GPS more! Charlie
