Re: Water Pump replacement 1987 SPL 88 horsepower Evinrude outboard Motor
No I haven't got the lower unit off. I definitely will though before I go boating for the first time. Rodbolt You were asking if I was going to change the Thermostats. I was just going to go ahead and replace the water pump only. I didn't think the thermostats needed to be replaced also. I will go ahead and buy the original water pump kit from a marine dealer for Evinrude motors. There is a Cope Marine dealership here in O'fallon, Illinois. This<br />way I don't have to do any modifications to any thing. Just take the old pump off and bolt on the new one without drilling modifying etc. Is this what you would suggest.
?<br /> for the jonny rudes the napa number seems to work well. one of the few sierra parts I will use. try a napa number 18-3392. are ya gonna do the T-stats as wellas the pump? if you use the BRPparts the t-ststs need tobe notched if they are not from the factory . my preference is the sierra part # 18-3553 t-stat and you will need 2 of them, what I do if going aftermarket is use the auqa power part # 2658 t-stat kit and use 2 18-3553 t-stats. unless the kit now comes with self flushing vented t-stats. I have not bought one in the last 6 months or so. also modify the t-stat housing vent. its a small hole at the top almost center. drill the vent out to 1/8th. or your next post may be runs fine for 3 min then the hot horn sounds. let it sit 5 min and its fine the rest of the day.
