I have a Yamaha 2005 115TLRD 2 Stroke. When I get on plane after about 10 seconds a continuous alarm goes off. I have done the following already. 1. Installed new water pump kit. 2. Installed new thermostats. 3. Installed new poppet valve. 4. Flushed the cooling system with Rydlime Marine descaler for 4 hours. I mix the oil with the fuel directly 50:1. Tell-tail has a strong stream. Any ideas? Thanks.
