  1. Thank you for your reply. I don't see where I stated that it is a Bravo 3. Sorry. Just yesterday I have removed the housing and inspected it for any blockages or build up. While idling the thermostat does open "I also checked it in a pot of water on the stove" I checked the sending unit which works perfectly. The Engine Coolant Sensor and gauge sending unit record water temp from the shared water jacket. I thought of switching the two on the housing to rule out the possibility of obstructions or air pockets at the sensor. Do you think that should be my next troubleshooting task?
  2. Did it ever overheat due to a raw water pump failure? I had the same issue after my raw water pump failed and I pushed the boat to the limit, I should have had someone tow me in but that dock was sooo close. Lack of water flow through the exhaust risers is the only thing I can think of to cause them to melt.
  3. Hello everyone. I have a problem that I cant seem to get to the bottom of. I have repowered my 1998 2335SS, 5.7 EFI gen+. Bad riser and leaked into the cylinder through the exhaust valves rusting the pistons to the cylinders. New everything except alternator. Serial number OLO12155. I put her in the water two weekends ago and ran up and down the river for a good day of break in. Ran perfect like the new engine it is. I kept everything basically stock. I am running at about 70PSI oil pressure, 170 to 180 temp with a 160 thermostat depending on the load it's under. I only idled it through the no wake zones and back to 2500 through 3800 rpm during the eight hours of running we did. Put it back on the trailer and headed home to wash and flush with fresh tap water. Nothing changed until this weekend. Same thing, put her in the water ran it hard for a while. half way through the day, alarms went off causing it to go into a sort of limp mode? idles fine in neutral and under load until the RPM hits 1800 to 2000. Alarms constant until I limited it to the 1500 RPM range. looked up in my manual (service manual number 24) the diagnostic test for the trouble code 14 "Coolant Sensor Voltage High (cold). I am using the Codemate ECM trouble code tool. As I followed the diagnoses tool and had the 12 code three times and then the 14 code three times back to 12 again. I replaced the Engine Coolant Sensor even though it tested at 2600 ohm range which is normal at outside temperature 80 degrees here today. I also checked the voltage with the key on and had the required 5volts between wires 410 yellow + and wire 814 black -. there are no reason I can find for this code. There are no water blockages pump works well and the oil pressure is great. This is a sensor that controls fuel delivery not the temperature sending unit to the gauge. I consider myself very good with engines and electronics. Auto mechanic for many years before I got my Masters License in electric. I'm not a professional marine mechanic but I understand all the concepts. I don't want to be a part changer so I am asking for advice as to further troubleshoot this issue. I guess the MAP sensor could cause this issue too but the trouble code is specific to the ECS. grounding is good the batteries are brand new and charged. This has to be a sensor causing the ECM to alter fuel delivery. Did I mention it does surge while it is alarm. I checked the Cap rotor and a couple spark plugs and all are in perfect new condition. I could see some misfire and rough idle if it were an issue with the ignition system but not a full alarm and change in fuel delivery. I have also checked the connections to the ECM (EEFI1 or 2 I'm not sure) and they are clean. I traced the wiring looking for any damage and found none. I really hope its not an ECM issue. The MAP sensor will be my next route. Thank you in advance for any direction that you can give.
  4. I have never forgotten the plug. BUTT!! Is exactly what I felt like, when I left the dock, planed out and a huge bellow of smoke from the engine compartment and alarms galore! To my pleasant surprise smoke was steam. Other boats were coming to my rescue with fire extinguishers in hand! Whats worse than forgetting to put in the plug? How about leaving the cups on the out drive? That was my stupidest moment! New alpha out drive water pump, fluid changes, and back on the water. At least no permanent damage done except to the ol pride.

    Hello everyone, I'm a newbie to the forums but not so much to boating. My first Chaparral was a 1980 something 185 bow rider with teak platform and trim. A LOT of maintenance. I was 18 years old then and I had then energy to keep up on the maintenance. I now own a 1998 2335 LE sport, 5.7ci. EFI with the Bravo3 Dual C.R Props. I am the second owner, bought it in 2003 and the boat has been perfectly maintained. That being said I am "like many here" O.C.D. about keeping the boat mint clean. I just spent 1.5 days with the Meguiars three step system of cleaner wax, wax, and polish. I keep the boat trailer-ed and the hot and humid conditions here in southern Maryland ,in the 90's today, has been harsh on the blue areas of the boat. Oxidation has begun to beat me down. I wash and wax religiously. like I have read in the thread, My link I also have a two beer per hour quota I have to fulfill while rocking the classic rock tunes. This was a great read. My question: Has anyone tried the VERTGLAS Gel Coat Restoration System? I am looking for any pros or cons about this product. The pictures and testimonials are very promising. I want to give it a try but my experience "Too good to be true!" Here is a link to their product site: My link I also have to remove my dash & steering wheel plastic trim so I can fill some cracks in the wood grain finished plastic bezel, lightly sand, prime, and paint white. Also sun damaged. I have the boat winterized, cleaned, waxed, and shrink wrapped for every winter storage. Any advice about this product would be appreciated.
