Sierra 23-7800 is an engine oil filter cross referenced to Westerbeke part 36918. It is meant as a direct replacement for that original number. The fit list covers several Westerbeke model families, among them the 4.5 BCG, 5.0 BCG and 6.5 TWG, each with its 60Hz and 50Hz version. Sierra says to check its catalog for current application information before you buy.
Our take
The Westerbeke 36918 cross reference is the useful part: if that number is on your engine's parts list, this filter is the Sierra match. The fit list names 4.5 BCG and 6.5 TWG models, but Sierra still sends you to its catalog to confirm.
