Ser# 2B399392 Mod.1251P73BD Had smart craft alarm, starboard thermostat improper function. (Non critical) Noticed water pres. at idle 0.9 - 0.7 psi. checked , cleaned Strbd. thermostat, new gasket. (no debris) Cleaned strainer, Very minimal debris. Installed new water pump kit. old set had paper/silicone gasket blown out in small corner section. Drive shaft seal was approx. 1/4" from touching top of impeller housing. Next outing noticed water pres. still 0.9 / 0.7 at idle. Pres. increases will rpms. reached 18 psi. Lake to rough for WOT. End of day let idle waiting at ramp and alarm went off. water pres. 0.9 /0.7 Again starboard thermostat improper function. Didn't think to take note of engine rpm at idle. Pulled lower again to see if I had forgot to tighten impeller housing bolts. (all tight) But did notice couple drops of Opti DFI oil on top of clean impeller housing and at top of now clean drive shaft. hoping this is normal. but I pretty sure its not. will take note of idle rpms this weekend during (must fish) tournament. Is there a lubrication port for driveshaft / crankshaft / spline connection. Thanks in advance
