So we purchased our '96 330 Sundancer in October of 2020 but didn't drive it until spring of 2021 and I did not remember it steering so hard on the sea trial (I really only drove it on the open water). The steering took two hands to turn it so, took apart what I was able to access and applied some Quicksilver grease, it was better but still two handed steering. So started down the path of hydraulic steering and wondering if it would be better than the current cable/rack system or not? So we (me) decided to upgrade the boat to hydraulic steering and we wanted it to look as factory as possible, you be the judge
I started out by sourcing all of the parts and here is the list I was able to come up with:
Fogot about the steering wheel, was lucky enought to find a '06 380DA wood wheel on the forum and that completed the build. (Thanks Sam W.)
BTW, the 1.4 helm and BA125 cylinder is what came from the factory but it was borderline for a 33' boat, ratings had it at 32' so I opted to go one size bigger on helm pump (1.7) and cylinder because that is how I am
**Warning - Don't make the mistake I did with the hydraulic lines! I followed the book and kept starbord on starbord side of helm/cylinder and port side on port side of helm/cylinder just like the book shows! BUT, what I didn't notice was book shows rudder arms pointing forward toward the bow and on a '96 Sundancer they point to the rear or transom so YOU HAVE TO REVERSE THE LINES at the cylinder!! I did not catch this and steering was backward, it took me two days to figure out why, I checked, rechecked and traced out the lines (major pain in the a$$). I had put green and red tap on the lines before I ran them and ran one at a time but when we were finished the rudders turned the wrong way!! Wife was like "told you should have paid to have this done"
Switched the lines at the cylinder and all good, turns correct direction.
Total upgrade cost was about $2500+ and worth every penny!! One handed steering around the docks and looks better than the black rubber wheel that came on the boat.
If I had to do all over again would do it in a second, the results are very worth it!
I started out by sourcing all of the parts and here is the list I was able to come up with:
- SeaStar HH6541-3 Classic 1.7 Tilt Helm (www.seatechmarineproducts.com)
- SeaStar HC5313-3 Inboard BA135-7ATM Hydraulic Cylinder (SeaTech)
- SeaStar 90 degree pivot elbows Model#16275190 (West Marine)
- Note: They come with the SeaStar Helm pump so don't buy extra like I did.
- SeaStar Hydraulic Nylon Tubing 50' Model#4732111 (West Marine)
- Tried to go with the SeaStar premade lines with the nice BIG molded ends but could not get them thru the boat to the back, no room and very tight spaces. Returned to West Marine for $160 return. And I ordered 18' but should have gotten 20'
- SeaStar Hydraulic Steering Fluid Qty:2 quarts (West Marine)
- Bronze Rudder Support casting #27635 w/hyd-cyl mount (purchased used on forum)
- This part replaced the original #27416 upper support which came stock for cable steering.
- I had a heck of a time trying to find the correct casting # for the upper support with the cylinder mount built in as seen in the photos.
- This part new from FP was just under $700 with shipping and did not have in stock and they could not confirm the part number fit my 330DA.
- Wasn't sure it would fit, nobody could confirm if #27435 was the correct one so took a chance and bought one on the forum off a parted out 2003 320DA.
- To make sure it fit I placed the new on over the old one and perfect lineup!
- So the correct replacement is bronze casting #27435 (forget the Sea Ray parts manual, those numbers only make sense to Sea Ray)
- Tie Bar or Jack Bar tab, bought from Summit Racing $5 (used in race car chassis)
