Yanmar 3YM30 - Still need a High Rise exhaust mixing elbow?
whitepointer replied to Adrianp's topic in TechTalk
I've had a HDI 3YM elbow for a few years, no issues, motor mostly running in the 2500 to 3000 rpm range, -
I've never had an impeller fail,i change it yearly though, keep the old one for a spare, had one where the pin had worked its way out a bit, I fitted new pump because it wouldn't prime itself after impeller change, had a fair bit of wear in housing, put some rubber grease in and it would seal good enough to start pumping , then it was OK, but it was original 2007 pump, so fitted a new one to be safe
-
New impellers usually come with a little packet of lube , I also just sources a new raw water pump from Energysystems.com.au for my Yanmar 30 3ym , pump has a mechanical seal fitted, and can use the std yanmar/johnson impellors, $740 delivered
-
I agree , costs more to buy the pack than paying the pros
-
I moor in HMB marina, have good results with prop speed on my kiwi prop, good for 2 years , boat gets regular use, HMB boat spray apply it, had boat for 12 years,i grease prop once a year,
-
Had a lovely sail from Halfmoon Bay marina to Chamberlins Bay at Ponui Island today, nice SW breeze and flat water, 10.5 knts top speed with main and poled out headsail, about 2.5 hrs for the trip
-
Any recoat of different antifouls should have a coat of primercon first I would think, that's what I would do, I have applied warpaint last October, over new epoxy barrier coat, happy so far
-
I noticed Mayor Brown had a RNZYS cap on the other night, wonder if he's in support of the hardstand?
-
Another option is to book a berth in opua marina for a few days, great facilities, we did it a few years ago during a blow, hired a car and did some sightseeing in northland
-
Opunga cove BOI is a good spot in easterly blows
-
Just do I, I spent a lot of time fretting about the money side of it, and how we could afford it,11 years later still got the boat and enjoying it
-
I procured an HDI marine exhaust mixer for my 3YM yanmar a few years ago, arrived within a week , via Australia I recall, same price as yanmar part but better quality
-
We came back a few days ago from Rotoroa, had an interesting night in north harbour when wind changed from SW to E at 4am, had a few big powerboats anchored really close, but no major dramas, we have no fixed timeline so back in the marina u till favorable weather arrives
-
After a few years of procrastination, finally got into it and scraped many layers of antifoul off Whitepointer, what a slow laborious job, 6 days to scrape and another 4 to fill and sand smooth ready for bottom paint, im very happy with the result.
