Recently purchased a used 2000 MB Sports Boss 190 with the GM 350 5.7l V8. Took it out a few times now and each time it runs GREAT!.. for a while, but after about an hour, the motor starts loosing power while cruising. It Bogs down and if I don't pull the throttle back to idle or neutral, it dies. Starts right back up without hesitation and idles in gear just fine, but once the power loss starts (after an hour or so of operation), it wont maintain any speed above 1k RPM and will bog down again.
I've replaced the fuel filter, low pressure fuel pump, high pressure fuel pump and spark plugs and it's still happening. Engine temp on the gauge is constant 160 with no indication of overheating. Oil pressure seems normal. Any ideas what else could cause this issue? I'm stumped!
I have a 2007 F23 and am having an issue with water pooling up under the front cushions. I was reading in here where someone had talked to MB and they told them where to drill holes in each side to let the water drain to the back. Can someone help me and show me exactly where to drill holes?

I realize that I am posting on a MB Sports forum and I understand that some of the answers might be a little biased... But I really need some advice.
Looking to buy a 2018 Boat. $80k~ Budget
My time on water =
70% wake surfing
10% wakeboarding/ tubing etc..
I want a 22 foot or larger. I hear 21 foot boats tend to have a little more difficulty with wake surfing / water displacement.
I have looked at every option out there and I have talked to several dealers.
I have a fantastic Malibu, Supreme, Centurion and MB Sports dealer right in my area. So these brands appeal to me a little more..
I want a good out of the box wake surfing boat. I don’t want to add ballasts (like I did with my previous boats) or heavily modify my boat. I am spending a ton of money and I want for it to be right from the start.
Any opinions out there on what I should look at?
I am highly considering a Tomcat F22 (due to price, looks and being a local west coast company) but the other day I went and looked at a Malibu NXT22 which also looked great! The dealer told me that It would be just a matter of time before I upgraded to a Malibu... and that I would “like” my MB but not “Love” it. (I know they were trying to sell a boat but maybe they were right?)
I have watched countless videos on performance and quality. I just want real owner experience. Is MB the way to go?? Please help!!
This is the first surfing boat we've ever had. Before this we had a 1994 Malibu Echelon for slalom skiiing (which the MB is still great for btw), and we got the MB brand new in 2014. This is the first time we're trying to add aftermarket ballast, so we're new to all this and just bear with me!
So I finally learned to surf without the rope, and I was using only 900 lbs of factory ballast. Now i'm researching and found out it's way easier when you have a bigger wake, wish I knew that before haha. So can someone help a girl out and explain exactly what type of ballast bags I should get, and where I should put them? A lot of places say to put it in the rear compartment near the engine, on one side, then others say to put it in the bow for a longer wave. Which is best? Do I do both? Should I have the dealership put them in/ consult me on this or is that unnecessary? Trying to be cost efficient.
What ratio of factory ballast verse bag weight verse weight from people/gear did yall use? Trying not to sink the boat.
I was looking at the ballast bags on https://www.wakemakers.com/wakeboard-ballast-bags?gclid=CIznlePQltQCFRiewAodOUMFWw is there a certain one yall have used for your MB and like? Are they easy to use/ could you fill up and drain quickly?
Also, can someone explain exactly what play and plug is? Does my 2014 B52 21' have it? I saw that MB just added play and plug to their 2016 model, but on another thread on here someone said their 2014 has it. I understand that if we got ballast bags we would have to manually pump them to fill/drain, but with play n plug you hook the bags up and the boat does it for you....is that right?
Also how necessary is it to get GSA plates, and what exactly do these do? We surf mainly in the summer, not year round, so if these are wildly expensive could we forgo them?
We LOVE the MB and are excited to get a bigger, better wake. If you see in my picture, our wake right now is pitiful. Surfable, but difficult.
I attached a picture that I found useful of where to put the bags, but it's not specific to B52 21 and it doesn't say how much weight I can have.
The second picture is a screenshot from https://www.gosurfassist.com/boat-ballast-setup where it tells you only put 750s in the back and none in the front? I thought that was weird. Also it tells you to fill up "all the factory ballast", which would mean filling up both sides and from what I understand you only fill up one side? Again it tells you to put bags in both sides of rear which is weird to me.
Any help much appreciated. Thanks!
