    Engine re install.

    I am nearly done with the stringer/transom/deck replacement on my Sangster 21. I6 with MC1 outdrive. Does anyone have any advice for the re install of the engine for me? The front mount was lag screwed to the engine bed originally(as I found it any way). On re install do I gently lower the...

    complete rewire

    I am doing a complete re wire on a mercruiser powered 21 footer. The engine is an inline 6 that I am adding the petronix electronic ignition to. The stock wiring harness is toast and I plan to re wire it myself. Does any one know of any links or resources to help me design the system, I do have...

    Flush deck hatch

    I want to install a below deck fish hatch in the 21 Sangster hardtop I am restoring. How do I make the hatch supports that will allow rain water to drain to bilge rather than into the fish box? Do I make up a mold and do a fibreglass layup or just make them out of wood and then chop strand to...

    parts list

    I am rebuilding a 1976 Sangster 21 hardtop, power is I6 and MC1 outdrive. I am well into the transom/ stringer/deck replacement and it looks like next weeks weather may convince me to look at collecting parts to put the outdrive back together. I will need all the parts/gaskets to re install the...

    below deck fish box

    I have a section between stringers about 36 inches long that I can use as below deck fish locker. I am replacing stringers and deck so I have a clean slate to work from. I have done some searching but have not found what I am looking for. I don't see any manufactured hatches big enough so I will...

    capping stringers

    Is there some special technique for this? I have 3/4 ply stringers, I have tabbed them in place with 3 layers of 1708 and I need to cap or encapsulate them now. I have a hard time with the 1-1/2 oz csm. I can't always get it to lay flat on the radius on the top. The guru at the plastics store...

    MC165 Engine bed height

    Uh oh, I can't seem to find some of the notes I made when tearing my boat down. How do I go about figuring out the engine bed (mount) height. I specifically measured down from the gunnels to get the vertical position of the front engine mount for my Mercruiser 165 I6 engine, unfortunately not so...

    Fibreglass materials

    I have tabbed in my transom, and am ready to start on my stringers. 18oz roving is 8$ a yard, 1-1/2 oz CSM is $6.30 a yard and 1708 is $15 a yard. As I understand it, you need to layer CSM in between layers of roving. This totals $14.30 a yard and is only slightly less than using the 1708. Seems...

    Scuppers/deck drain

    I am doing a complete gut on my 21' Sangster hardtop. There was a notch in the engine box near the transom on the starboard side of the boat. Looking at my photos, I can't quite figure out what the purpose of it was. Any one know if it is needed? I think it may be clearance for the trim pump...

    transom keyhole

    I am going to work on the transom this weekend. I plan to oversize drill the transom mounting stud holes so I can fill with resin and then drill to size later. Is this an overkill procedure? I can use the transom skin as a template for the holes and the keyhole, but it will be a trick to drill...

    Transom repair - extra holes.

    I am rebuilding a 21 foot fiberglass boat. I have the hull gutted and ground to bare glass. Over the years there have been an awful lot of holes put in the fiberglass transom skin. I would like to start fresh so to speak and plug up all the un needed openings. What would be the best way to go...

    Sangster 21 Restoraton

    Picked up the boat and trailer about a month ago. Pulled the engine and started gutting. Boat has the classic inline 6 power plant and a mercruiser outdrive. Boat will be used for fishing on Vancouver Island so it needs to be built strong.

    how far to grind?

    I have my boat gutted, stringers wrestled out and started grinding. I will post pics tomorrow when I get my camera back. How much do I need to grind to replace stringers? Do I aim to remove all of the original tabbing or just grind to clean well bonded fiberglass? The boat is a 21 ft Sangster...

    trim switch

    I am in the process of doing a restore on a 1976 Sangster with the 165 Mercruiser 6 cyl and MC1 drive. I have the trim limit switch in the outdrive not on the bellhousing pivot. I understand you can't get the switch anymore. I also have the hydraulic trim position sender. I am doing a complete...

    Bellows install tool

    Soon I hope I will be putting my transom assembly back together. My question is about the bellows expanding tool. It appears that it is an expanding pair of pliers with a semi circle on the outer ends. In use do you hook onto one of the folds in the bellow, expand to get grip and then use it to...

    Testing manifold

    When I pulled the engine out of my new to me boat, I noticed some coolant in the bottom of the manifold where the riser bolts on. The manifold is in the closed loop cooling system, there was a block off at the riser to prevent the coolant from exiting down the exhaust. Any way I made up 3 block...

    Gimbal disassembly

    I am trying to disassemble the gimbal ring and housing. I have looked at the manual and am still a bit fuddled. I think procedure is to remove limit switch, remove allen head screw on gimbal ring. I have torched it and still no luck removing it. Perhaps an impact would shock it free... of course...

    Bell housing crack

    I am taking apart the transom assembly of my new to me old boat. I wanted to replace all bellows and gimbal bearing for a bit of a fresh start. Engine is a 1976 mercruiser 165 I6. Drive is of the same vintage so I believe it is MC-1. I removed the pivot pin and discovered a crack in the pin boss...

    water pump I6

    Hello, I have a 1976 Mercruiser 165. I have the engine out of the boat and would like to replace the inblock circulation pump while it is easily accessible. Can I go to an auto parts store for this part, or does it need to be marine specific? The engine does use a heat exchanger, so the pump...
