1974 170 rebuild

[rebelionshot]

looking good so far.. i just picked up a 73 170 myself that needs some floor work. i have almost my whole cap loose except where it is on the transom which i will have to figure out where i am going to cut it.. do most of these boats have flexible sides behind the rod holders? my sides were able to be pushed in fairly easy before taking the cap loose..

Yes they do, the hull walls and cap walls are only a couple sheets of matting thick. And with it being 45 years old it's probably a little more flexible than fresh from factory. The integrity of  the glass is still great though. I'm adding layers of 1708 to mine because i will not be having my deck connect to the floor and will be braced like the larger models.


I've almost got the whole thing laid with new glass. One more after work session and the center stringer will be finished and start working on rigging tubes and fuel tank.

gotcha yea i figured if i was going to redo the floor i might as well bite the bullet and pull the cap so i can reinforce the sides since they are without a doubt flimsy over the years

Well after a few months of fishing non stop, I've had some time to work on my own boat a little bit recently. We also just had our baby girl who's 3 1/2 months old now so time was non existent for that past few months anyway.
                                                                               
I finished glassing the stringers and outside of the hull then ran some some rigging tubes and filled in a little bit of foam. Never really got a picture but also put a brand new fuel tank i built in that measured 58''x20''x10'' I think the exact measurements came out to about 39 gallons give or take. If anyone wants to see pictures i can find some. 





Then cut out the deck with 3/4 foam and joined it with strips of 1708 and then put a single layer of 1708 on the bottom and 2 layers on top.










Then I decided to trash the old cap and make a new one out of 3/4 marine ply. I was going to do it with foam and save some weight but I would rather have the strength from the wood. I cut the pieces first and than glassed them with 1708 on top and 1.5 oz cloth on the bottom. I really wish i glassed the whole sheet of ply first and then cut. Lesson learned! Would have saved me a lot of time but i did remember to do it for my support braces and made templates and cut them out of a pre glassed sheet. Also made a mock up of my planned console for size and weight distribution reference.









Today and yesterday i glassed the deck down with thickened resin on the stringers, foam, bulkheads and floor supports. i didn't get many pictures of what everything looked like before i put the deck down. I painted the bilge with grey epoxy bilge paint and added 2x2 supports that i glassed to the outer skin for the edge of the deck to sit on and then covered everything that made contact with thickened resin (cab., teak shavings from another project,and fiberglass dust) pretty much just made the muddiest thing i could. i probably used 2-3 gallons of resin. then put a ton of weight on the whole thing. It's been cold so i mixed it hot as hell and it still took all  night to kick. the next day I filled the gap with the same stuff and used a 2'' pvc pipe to make a nice transition and used 4'' 8oz mat tape on the seem and some 6'' 4oz mat tape over that. Aslo glassed in the bow supports and the front anchor locker bulkhead. Then mounted the motor and splashed it to see where the waterline was... I forgot to seal my thru hull fittings first  but had a few minutes to see how deep it was sitting and it looks like the scuppers will be above water.  That's all for now! Time to go back to work for a few more weeks and plan on the next few pieces before i start fairing.










Still tweaking the gunnel supports before i glass them in. I might build a couple out of teak for the midship rod holders and ill be boxing in the transom corners for clean covered rigging tubes. and storage.


I also finally bought an engine!! (the one pictured) a captain in town took it to a local mechanic and they said it needed at least $3k in parts and labor so i got this engine for a steal for just $1k! I had it on a stand, hooked it to a battery, and the only info i had was there was a serious wiring problem. I tested the compression first, changed the oil and cleaned on plugs. i jumped the starter with a test wire and it started up first crank. In my diagnostics i found the the positive pin on the wiring harness plug was rusted and the rectifier plug had the same problem I ordered a $500 new wiring harness from Boats.net and a new rectifier and it's good as new now. So i spent $1700 on a great running 115 yamaha 4 stroke with perfect compression. Gotta love the shatty lazy mechanics of the florida keys!

Wow, that's a lot of progress.  Looks good.

[hudsport]

Okay so it's been a long season, i've fished everyday since April and summer is finally almost over and it's time for slow season boat work again. (Unfortunately, it's still 90 degrees) It was a fun summer though! I spent two months in the bahamas and two weeks in Cuba. I caught 40+ marlin and many of slammer dolphin over 50lbs! I've got loads of pictures on my Instagram if anyone wants to check those out or link up. @corryyyyyyy
But anyway, I did a bunch of stuff to the boat over the past few days. I made the console out of 3/4 foam and glassed it in, ran necessary lines for a sea trial (stearing, battery cables, bilge pump, guages, etc) i wanted to do some sea trialing with the boat since i did so many modifications to the original 170 design and added a 115 4 stroke. im going to take it out in various conditions over the next week or so and make sure all my glass work isn't cracking or pulling anywhere, make sure weight is dispersed evenly, and pretty much figure out how i want everything laid out before i finalize and start fairing and painting.. and im sick of not being able to take this ting for a spin so i got impatient and decided to go play. Heres what i've got for pictures. Let me know what you think!

BTW: anyone that doubts putting a 4stroke 115 on it sould try it out, im sitting 2'' inches above the waterline, even with my 240lbs buddy and I(170lbs) two AGM 31 series batteries(120ish.lbs), 120 Yeti filled with tools(80lbs) and a 39gal fuel tank. (The bottom of the tape in the pictures is the previous boot stripe, the top of the tape is where the deck sits)

Oh and i was running dead nuts 40mph at wide open 5800 and about 27-30 at 3500 no porpoising due to having the added weight up on the bow with the console being so far forward. i want space in the stern not the bow, hence why i put the console forward. and it'll have a 100 gal well as a seat in the winter for sailfish. overall i am very impressed. this is my first build but i owe it all to the hull, such a great design. It slid a little in turns while going fast but digs down good if im going under 30

Your boat is looking great.  Those are some impressive performance numbers too.

She's coming along nicely - good job.
