Re: Talk to me about the CT38 (Warwick design)

These boats perform well in our club racing and as she has a GRP hull there is no reason to believe she would be any leakier than any other glass boat of this age. There is a lot of teak on the...

Re: Volvo MD17c water pump

The pump should be fine for wear if it was replaced in 2009 although impeller replacement could well be required if you have overheating issues.

Re: Compression Test for Volvo 2003

I am guessing that this will be a 30hp or 44hp engine either three or four cylinder?

Re: Prove or disprove Volvo

This wear looks normal to me, where ever the seal lip runs will always take some polishing/wear and is to be expected. Fit new seals, know what type of seal is being fitted (sprung or unsprung)and...
