ran today to get up to 5 hrs on rebuild
95 mariner magnum 200 / 190 DCX
25M @ 3.75" below pad
52-54 mph GPS
5400-5650 RPM with tail at top of cowling
water temp 43 / air 58
loaded full everywhere except gas (12 gal)
rooster tail blows out way too high well below neutral (half way) trim on indicator
best tail at about 1/3 on gauge
This is not what I was looking for, but it is what it is. I'm hoping once I get off this double oil it will have more thump. Will this get any better?

Those aren't good numbers at all I don't think. I had a 181 with a 150 that would run 64 and change....
That's what I'm thinkin too. My 82 Hydra-Sports / 150 was better than this.
I'm hoping somebody will say its just the oil ( ...but I've got my doubts)
first lets get through the double oil and get atleast 10 hours before we get too worried, then lets put new plugs in her. Finally find a Tempest 23 or 25 that is known good and go get some new numbers.
how far back on the pad was the water exiting - I'm trying to get an idea if you're getting a lot of lift and actually getting the boat back on the pad.
Peace,

Thanks for the advice Don.
I'm not jumping off the bridge yet - just disappointed. I've waited a long time to own a Champion. Its under warranty and I don't want to miss getting something fixed if its needed.
I missed the last part of your post - sorry.
I did notice the water breaking pretty far forward, out at about my console with a good, low tail and maybe even with me when I pushed it up to the cowling top or a little higher. To get it back any farther the tail looks like a fountain. Seemed way too far forward to me, in my opinion. Prop is in very good condition visually - no dings at all. Setup height is about right from what I've learned. Hard to believe its this out of whack -
get it good and broke in and then try raising the motor some and see what happens
Thanks Luke.
I'm pretty close to the bottom of the slots on the plate. Maybe 1-1.5 inches left to raise the engine. Does that sound normal for 3.75 in below pad?

That set up needs a tempest prop. Pat will be along to give you more specific advice on that rig. BTW, the 200 2.5 l mercs are usually strong engines so something is not right I would agree.
Do you have a jackplate? Your comments about the bolt holes prompted me to ask.
We need to find a way to get you more lift, water should be exiting behind the drivers seat, the further back the better.
BTW those old hydrosports were a blast. I fished out of a friends in East Texas for several years and with a little chop on the water they would flat haul the mail.
Peace,

Larry,
Have a CMC 6" power-lift plate and water pressure gauge. When trimmed in to load the engine I get over 20 lbs at high end of RPM. Trimmed up its not that impressive - around the minimum pressure 14-16 max
Water is definitely breaking out in front of me for everything close to ok trim. I don't think I ever got it loose on the back of the pad because I lost my bite.
BTW - That old boat was fun. I had an X-270 with a pretty virgin 150 Black Max/Predator worked by MAZCO. It would hurt you in any rough water, but more than a few guys watched me pass 'em
Either your prop is crap or your not really 3.75 below the pad. You should be able to run that rig at full trim at 3.75 below pad without an excessive rooster tail with a good prop. Borrow a known good prop, double check your engine height and see what happens.
My other boat is a 1994 190 DC. I also owned a 1991 190. I had a GT 150 on the 91 for a short time and it would beat those #s.

I've checked and rechecked the motor height - its very close to 3.75" below the lowest point of the pad. My measurements do vary between 3.75 and 4.0 depending on the length of straight edge I use and eyeballing "parallel" on the lower unit. Most often its 3.75 to 3 7/8". Assuming the prop is "good" the symptoms seem to call for lowering the motor - which doesn't fit the expected setup for a 190/200 EFI.
We need Pat Goff to chime in here....but I have to think your prop is not good.
You need to get an EXACT prop to pad measurement. Trailer on level ground (carpenter level on ground), trailer level using jack to adjust (use carpenter's level on frame), motor trimmed down so cavitation plate is level (also using carpenter level), measure from lowest point of center of pad to ground....(forward of drain and livewell holes), and then measure from center of nose-cone to ground. The difference is the prop-to-pad. I am not trying to be condescending...but many folks don't know exactly how to measure....and even as little as 1/16" makes a huge difference.... "eyeballing" is not good.
Hang in...our folks will get you set...
I had a 97 191 dcx with a 200 (2.6) yamaha, 10 inch j.p. it was 3 1/2 below pad & ran mid 60 gps. It was load sensitive, be sure you have it balanced. You may need to try a 23 or 25 tempest.
befotre i would really start getting worried about it to much get it good and broke in then start messing around with it....im like everyone else i think your prop aint the best but it dont take a lot for a prop to be off...even a small nick in the blade can make a pretty big deal....and then once its good and broke in we can get some more info on it and go from there
Thanks everybody. I'll go the extra length to get better measurements before I go off the deep end and take this engine back. My prop is visually flawless - not a scratch; However, it was sent out to be "cleaned up" prior to delivery. Maybe it was/is way out of spec for a 25M. John Mazar/MAZCO is real close by and I don't expect to get around prop work to get performance, so thats OK. My thing is I want my dealer to handle ANY/ALL problems related to the engine - since I bought this boat w/o running it due to the engine being blown in one hole. I'll keep at it.
All your inputs are appreciated.
Jeff
