Additional Notes

Complaint: I took my ************ in for a front gasket oil leak. After paying 2551 for repairs, the engine blew on water test. Now they want another 2k On 8/13/14 I took my ************ RXT into The Ski Clinic for a front gasket oil leak. I was informed there was a 2nd leak and engine would need to be taken apart, it would be another $800. Upon taking engine apart the tech, ******* informed me that parts from old super charger were found and a clean out of engine was required. I had super charger replaced 2 yrs prior with Lodi Sea Doo, who told me engine was clean on replacement. I agreed 2 clean out. The damaged parts, oil leak and clean out increased my total bill to $3551. I brought ******* a single trailer to do a water test which he admitted he did not do but ran the engine for 1 hr with a hose hooked to it. I picked the ski up took it directly to the water ran it for approx 10-15 min and the engine blew. I immediately reloaded and returned the ski 2 *******. He admitted he had a feeling something wasn't right when he gave it to me. Upon looking at the engine ******* said he found a hole in the engine block and a rod was blown. He has agreed to not charge for labor but is insisting that he did nothing wrong during repairs, he has stated, "You must have flipped ski and got water in the engine" and "It's just a bad ski", etc. I have never flipped this ski and it has ran great 4 the past 2 yrs. My friend **** ********, who works on boats was at the dock testing a boat and helped me bring the ski in. He states, "Something was missed on putting engine back together and The Ski Clinic should make this right as I would. I also talked with a man named ***** ****, who is a boat racer who owns an Autobody shop in Vacaville, Ca who also states, "It sounds like from what your describing something was missed when he took the engine apart and put it back together. Why isn't this tech making this right? He should work with a salvage yard like most of us do and fix his mistake." I'm not an expert in this field but I paid alot of money for repairs and took *******s word these repairs were necessary and that my engine would run better than it ever has. He still is in possession of my engine and not agreeing to a refund or to replace the newly broken parts. I need assistance in moving forward please.

Desired Settlement: I would like full replacement for all damaged parts and a 100 hour warranty for the previous parts as well as the new parts. I would like my ski to run "like new" as was stated by *******. Or I would like a refund of $3551 as well as the cost of a new engine block, tie rods and any other parts damaged. He has estimated additional parts to be between $2XXX-XXXX not including his labor. A new engine is approximately 10k according to the Ski Clinic.

Business Response: Initial Business Response /* (1000, 5, 2015/06/18) */ We are currently waiting on a return telephone call from Ms *******. She has left a message on our voicemail after hours stating that she would be contacting us on Friday 06/19/2015. Initial Consumer Rebuttal /* (3000, 7, 2015/06/25) */ (The consumer indicated he/she DID NOT accept the response from the business.) I have been in contact with The Ski Clinic and we are continuing to work on a resolution. Once the work is complete, the motor is running as agreed and written warranty is in place to both our satisfaction I will close my case. At this time however, I wish to leave my case open until the matter is completely resolved. Thank you.
