200 Black Max Low Water Pressure

Well motor is still getting too hot. Idk what else to do unless the mid plate is wrong, or we have a problem in the heads.

Well I think I we got it. Took the power head off again because I didnt like the look of the mate up on the adapter plate. Our engine is a 2.4 200, adapter is 2.4 but the exhaust bracket that the tuner bolts too is not. I believe it's a later model 2.5, it doesnt line up at all with gaskets. How can I get my hands on a 2.4 exhaust plate? I dont need the tuner.

You can't put a 2.4 on 2.5 exhaust plate. There in is where your problem lies.

I took your advice on the 2.0, got me a set of 39's.

Not sure if I have pair of plates here at home to show the difference.

Are the older 2.0 plates same as 2.4?

We found a 89 2.4 mid local. It has the exhaust plate and tuner along with newer trim. I'm snagging the tuner, mid and trim my buddy is taking the plates. Should work out ok.

U dont want the 3 ram. Keep single ram if that's what u got

**Capt.Insane-o** · 11-12-2019, 10:42 AM

3 ram is much better for recreational purposes. Yeah you can't mismatch plates like that.

**TNRoostertail** · 11-12-2019, 11:21 AM

I have the single but I'm swapping to the newer boat and dont want the trim pump and all that stuff in my storage area if possible. It's a 17.5 boat and storage is limited.

Well merc turned out to be another single ram. I will holler atcha as I'm not taking it.

Ok we got the water pressure issue sorted out. On the lake now, holds 4-5 at idle and then a steady 15-20 wot. It's still overheating though. I'm pretty confident it's not a water issue now, the stats are opening and expelling hot water and pressure is very good. Could this be a timing issue? The guy that put this motor together before we got it obviously skipped some steps lol. What else could it be?
