external hoses on 87 evinrude 200 looper

[arhall]

This motor has small black hoses that connect each cylinder wall to the reed valve chamber of each cylinder. also #5 hose is also connected to a hose that goes to the upper and lower bearings.<br />What is the purpose of these hoses and should #5 cylinder be connected to the hose that goes to the bearings? VRO has been disconnected.I'm looking for reasons for # 5 cylinder to keep going bad.I need some help on this one.<br /><br />thanks<br />randall

Re: external hoses on 87 evinrude 200 looper

those are part of the recirculation system.<br />the ones you are talking about on the crankcase are valves. the ones by the cylinder are free flowing. the is a tool to clean them out.<br /><br />the screw in fittings have little screens that can get clogged with debree.<br />.<br />the book says<br />- to take a syringe with a clear hose, fill with isopropyl alcohol, connect to fitting.<br />fluid should not pass through the fitting. if it does replace.<br />-draw out the syringe, and air should pass through the fitting. if not replace.<br />-<br />the check valves also have to be checked<br />really need to get a manual.<br />the problem i found with the manuals is that the earlier versions dont get into the recirculation as well as the later.<br /><br />a 1994 "ER" gives a good description on how to do it.<br />a 1991 "EI" and below only gives you what i just did.<br />now the 1988 "CC" manual doesnt even give you a recirculator hose diagram.<br />if it was me i would go to ebay & try get the the year you need and look for the "ER" manual as well for future reference.<br />just trying to help
