engine overheating
I have been trying to get the manual or part catalog for the Yanmar
2GM20F but in Santiago Chile is a bit hard, Y have ordered it to Yanmar directly. My question...Does any body have a photocopy that can send me to my mail? I mean scanned, only the page where the heat exchange is? Thanks in advance Jorge -Genesis |

om... I have a yanmar 2GM20F installed in a Plenamar 300 with the following problem, No water coming out of the exhaust pipe with the result of overheating and the pump is working with a new impeller, what could be the reason for it and the solution. Thanks in advance Jzlatar-geminis 1 Check salt water intake cock is open 2 Check intake filter is not blocked (jelly fish, seaweed, plastic) 3 Open intake cock with filter out, check water flows. If it doesn't, there's an external blockage. If it flows, go to 4. 4 Detach outlet pipe from salt water pump, turn engine over (stop switch held in), water should flow out. if it does, go to 5. 4a If it doesn't, check priming height. Some pumps aren't very good at priming more than 2m. If priming height is OK, take cover of pump off and check pump vanes are turning. If vanes are turning, replace cover with screws only gently tightened and see if water comes out. If it does, tighten up and see if flow stops. If flow stops you've got a sheer failure in the pump impeller. The cause may be an overlength impeller, an impeller tight on its spindle, or an under thickness gasket. 5 If 4 shows good water flow, detach salt outlet from heat exchanger manifold, turn over and see if there's flow. If not, you have blockage at the heat exchanger inlet end (quite common) due to build up of carbonates. Clean out with reverse flow. If there's good flow, go to 6. 6 Check the exhaust elbow for carbonate build up and corrosion. That should find the problem for you. Have fun. It's called yachting. -- JimB Yacht Rapaz, sadly for sale: http://homepage.ntlworld.com/jim.bae...ecification.ht m jim(dot)baerselman(at)ntlworld(dot)com |

Most likely - fellow a few slips over found a jellyfish in his.

Engine overheating...PROBLEM SOLVED....... It was the exhaust elbow
that had carbonate build up and corrosion. Now the water really flows. Thanks to every body that collaborated with my problem.] Regards... Jorge- GENESIS |
