Ahoy mateys,

I've never owned a boat before, always wanted one, but started my family too early for that. Had a stint of a dirt bike hobby for a while, but gotta save on the body for work, so boating it is...or restoring boats it is for now. I Found her on craigslist, 150 miles away, listed first for 1500, then 900, then 500obo...I couldn't stop myself, I tried to trade the guy for a 68 dodge I had, but he only wanted engine/trans for a project. I hauled the body to the steel yard, got 300 bones for it, took the engine/trans to Belgrade, and came back with the biggest boat i'd seen up close in my whole life. I guess you could say I got paid 50 bucks to get it, since my trip to get it cost $250. :D

She's sat for a year and 3 months, so I've had lots of time to plan my attack. Heres what I've accomplished so far:
1. Contacted boat's former mechanic, Steve (Classic Boats, Somers, MT), who was more helpful than one could imagine!-SUCCESS
2.Tried to turn engine over with starter-FAIL
3. Sprayed PB Blaster in plug holes, soak, repeated crank test-FAIL
4. Began engine removal proceedure, learned all about closed cooling, manifolds, risers, and y pipes-SUCCESS
5. Stuck on outdrive removal, Used tractor to lift engine, wouldn't come apart...hmm, forgot inspection cover bolt lol-FAIL
6. Rigged up chain hoist to tractor bucket, took it slow, Engine out with no damage to boat!-SUCCESS
7. Removed manifolds, intake came right off, one exhaust manifold had rusted to the bolt, and required much force to break, damaged manifold-FAIL
8. Removed Heads, had rust in exhaust runners of nearest port to risers. Stern 2 Cylinders rusted tight.-FAIL
9. No longer rebuild, now its replacement, found a 97 f250 wrecked with 351w thats said to run good-600 bucks if I like what I see-SUCCESS
10. Countless hours of internet research on repowering the 233 Mercruiser wisely. Found awesome resources here and elsewhere on the net-SUCCESS

Plan A
Engine-Mercruiser 233 upgrade for reliability/tunability/mileage/power
*obtain running 351 from somewhere in Montana on craigslist; wont put it in unless compression is good, bottom end good
*rebuild current D0OE heads if rebuildable or get a set of aluminum or gt40 iron heads if not
*Install fuel injection manifold, injectors, rails, regulator, distributer(modified to marine), fuel pump&return, O2 sensors between manifolds and risers
*Control fuel injection with Megasquirt DIY ECU, tune with laptop mounted permanently by dinette as a dvd player/music library
*Order and Install OSCO or Barr center rise manifold/riser/elbow kit $750
*Flush heat exchanger, install hot water circuit for cabin heat/shower, replumb cooling system
*Replace damaged steel plate between engine and outdrive which i bent badly removing engine
*Install replacement engine and test

Outdrive-Mercruiser pre alpha 76 model 21p 3 blade prop
*Replace prop-$125
*Have skeg replaced at local weld shop-$100
*Replace little doodad on side of outdrive where the wires corroded it
*Fix leaking pump on trim cylinders, 2 lines
*Pressure test
*Run Test on muffs, check for water flow etc

Hull-Hand laid 22' fiberglass cuddy cabin
*Fix rub rail dent
*Refinish Swim deck, ladder, treads on gunwale, stern cooler/livewell lids
*Buff and polish gelcoat, fix any bad spots
*Reseal thru hull transducer? I dont know what it is, but its a teardrop shape sticking through the hull under cockpit
*Replace missing stern light, antennas, and hardware
*Silicone around all protrusions in back
*Install underwater lights on stern, bow to scope the bottom and swim at night;}

Interior-10 person capacity 4-6 person sleeping capacity(depending on relationship)
*Re-carpet stern area just up to hardtop(6-8'x8')
*have mooring cover stretched/repaired or buy a new one
*Build fabric camper top with aluminum frame, windows, and zippered openings
*Re-upholster back seats, engine cover, backrest, gunwales-everywhere any sun hit it
*Check freshwater tanks for leaks, replace hoses
*Test/repair alcohol stove
*Install stereo system-I'm young, we still like it LOUD
*Install mounts for laptop-to control efi and play music/videos, email pix, check weather, get repair info, etc
*Install new batteries
*Build better seats in back-loungers
*Test all wiring, replace lights with leds
*Rebuild missing bar(the only thing missing)
*Install cabin heater and curtains for open spot in hardtop
*Install hot water and mixing valve to operate a remote shower, like one you could use up on shore with engine idling

Trailer-76 Caulkins tandem
*Replace hitch/brake assembly
*Repack bearings
*Repaint
*find nicer wheels 13"


Well, thats the rundown, sorry to be so long winded, I've been thinking about this for a very long time!

Welcome aboard ditchrider,

Very familiar lookin boat type you got yourself...

Had a similar looking Bayliner, same year, sitting in my yard for a long time...it just got sold and hauled...

Congrats on getting your first boat...

Looks like you have been busy doing a lot of thinking and planning and getting ready...

You should load your pictures up in a free photobucket account and then post 'em here...

We like lots of pictures here...helps us to see what you see and be better able to give advice...

Seems like you have the engine/outdrive area somewhat under control, which is good, cause that is one of the most expensive parts of owning a boat...

The next biggest concern you should have on that boat is whether the transom, stringers, deck, bulkheads, and any other wood structures in it have a condition known as 'rot'...you can't just tap on it with a hammer...you need to do core samples of the lowest portions of the wood filled areas to be sure...

The wood rot usually gets in through water that has been sitting in the hull for any length of time and begins at the lowest points and works its way throughout all of the wood sub-structure...much like cancer, rust, or termites...once started, unless completely eradicated, will continue on...

If after you do core samples, and the wood comes out nice and light and dry, you just re-fill those core holes with 3M 5200 sealant/adhesive.

Hopefully, the structure is not compromised in this way, but you should check and be sure before you sink a ton of money and sweat into it...

Best of luck and have fun!

Regards,
GT1M
