mbslc Posted August 17, 2017 Report Share Posted August 17, 2017 I've been searching the forum for an answer to two questions. This is in regards to the 2017 MB B52 (23') with in-floor and dual 1100 lb ballasts. If you have some insight, I'd love to hear it. With the in-floor and dual ballasts full, the new 2017 B52 throws one heck of a wake for wakesurfing. However, I have two complaints: 1) The wake is mostly upfront and close to the boat. Not very long. 2) There seems to be quite a bit of exhaust in the face of the wake surfer. Any suggestions for how to lengthen that wake? I've tried moving people to the front of the boat, etc. Also, anybody else getting a lot of exhaust in their face when wake surfing? Quote Link to comment Share on other sites More sharing options...
oldsmobiledriver Posted August 17, 2017 Report Share Posted August 17, 2017 You will want a big bag full under the front seat and then a few people up front and youll be money! Quote Link to comment Share on other sites More sharing options...
Saguilar98 Posted August 17, 2017 Report Share Posted August 17, 2017 I don't have any complaints on exhaust but we are 50/50 surfing and wakeboarding. I guess if we were surfing all day I may notice it more. Anyway, take a look at the attached link. Some friends have it and said it helps. http://www.freshairexhaust.com/ Quote Link to comment Share on other sites More sharing options...
charvey629 Posted August 17, 2017 Report Share Posted August 17, 2017 This is the current setup that I'm running on our 17' B52 23'. Regular side Hard tanks full, PNP (port full & starboard 75%) Cav plate 40% 10.8 mph Goofy side Hard tanks full, PNP full Cav plate 75% 10.8 - 11.2 Keep an eye on your overfill port on your surf side to make sure it's not siphoning while surfing... You can usually tell it is by the wave shape change. I'm installing a non-return in line valve on ours to stop this from happening. Afraid I'll burn the pumps up by leaving them on all the time. Wave is steep and plenty long for us. Now, the exhaust SUCKS!!! We had our exhaust testing by indmar because we were concerned with the amount that was coming off our boat while surfing and everything checked out fine. The "exhaust" is actually steam that is produced from the CATS. It's harmless but truly annoying. We ordered a FAE and waiting on its arrival.

chico Posted August 17, 2017 Report Share Posted August 17, 2017 Keep an eye on your overfill port on your surf side to make sure it's not siphoning while surfing... Can you please expand on this? I'm not sure what you mean by "siphoning". I have a 21' and often hear gurgling sounds out of the overfill port and have seen water come out during sessions. However, this is on the non surf side.

Once the pnp bags are full and the pumps are turned off and someone is surfing, you can see the bags draining out though the overfill port on the surf side. Our hoses appear to be short and doesnt have a loop in the hose to prevent it from siphoning out when the boat is underpower. Does this make sense?

Sent from my iPhone using Tapatalk The gurgling sound is normal as that is the sound it makes when full, that port is just a vent, so as the boat rocks it will come out of that port if full.

chico Posted August 18, 2017 Report Share Posted August 18, 2017 Makes sense. I'll keep an eye out next time I'm out. Sent from my iPhone using Tapatalk charvey629 1 Quote Link to comment Share on other sites More sharing options...
OrangeTJ Posted August 21, 2017 Report Share Posted August 21, 2017 I don't have a B52 but we have that same ballast setup on our 16 F22. On mine, the key to getting it longer is to not fill the the PNP all the way, go faster (I'm digging 11.8 mph) and have weight up front. I'd guess that I typically have more like 700 or so in each of the PNP bags. I bought 250 lbs from Lead Wake that I run all the way forward under the bow seats and It really likes at leasst another 200 pounds of people of there (400 is better). That makes a very powerful, tall and long wave. I'm thinking with the 1100s all the way full, even more speed and/or even more bow weight would be necessary. Your exhaust issue may be simply due to the engine being pretty much maxed out with that much weight. Try lightening up a bit or adding more weight up front, as both will make things easier on the engine. Quote Link to comment Share on other sites More sharing options...
