What's the top speed of 5.7 1998 Mariah Z202. Just curious

Lots of variables going on there. Weight of boat, elevation, prop your running, etc. I would guess mid to high 40s possibly lower 50. You can search on here under propellers or tops speed and may run across someone running your similar combo with a posted top speed.

GPS verified, mostly empty my 98 z202 with a 5.0 could tickle 50mph, but could never get over it. Loaded down it was more like 46-47mph. I'm in WI at 700' above sea level.

That was with a 21' prop. I had a 23' prop with it too, but that was too much prop and I couldn't get the rpm's all the way up.

Agree with BlockP.

I've got a '98 202 with a 5.0. Running about 4,700 elevation my max speed is about 45-46 unloaded. That's running a hi-five 19, and not gps verified. Likely in the low 40's in all actuality. Loaded I'm lucky to get 40-44...

I have noticed a difference at lower elevations, but mostly just in acceleration and not so much on top end.

I have a 1998 Mariah Talari 221 with a carb Mercruiser 5.7 liter. With a 21 3-blade prop I am at about 52 mph and with my 15 4-blade prop I am at around 45.

Not bragging, but this last Sunday I hit 59.7 MPH (GPS Verified) in Lake Monroe - Sanford FL with a '98 Mariah 202 5.0L and 19* prop.... Wouldn't have been such a white-knuckles if my depth finder wasn't reading out 6.4 feet of water.....

Well with my new smart tabs installed I just topped out at 47 MPH GPS with a 14.5" x 17 x 4 SS prop. Boat had an average load of 4 people and 1/2 tank of gas. With the old whale tail I could not get it over 44 MPH GPS. I am at about 4800' in elevation. I was thinking about getting a 14.5" x 19 x 4 as a back up prop for Lake Powell, but not sure that would give me the power I need for water sports. Thoughts?

Not sure what water sports you are doing, but I have a Shabah 202 with 5.0 and a 14.25x21 three blade. I also run smart tabs with 80lb piston on hole 1. I have no problems pulling single and double tubes. I can cruise around 15-20 while pulling. Getting an adult skier out of the water is doable, but may be difficult for a novice. Slower driving for say a wakeboard I have not tried. Hope this helps!

Just noticed that was you Firestone. Did you like/keep your tabs at hole 2? I like the way 1 performed better than 3 for me, but have not done any measured wot passes yet. I was lightly loaded and want to test with more realistic loading in the boat. Have a safe and fun fourth!
