Outboard Motor Pod Advice

[cowan-cowboy]

Hi All,

I have an old Prongrass Surfmaster about 4.2m and would like to put an outboard pod on with swim deck for my winter project. I have got the bulk of the material and am not too woried about the cost as such as it is more about doing a project, creating some more space on the boat, putting a larger outboard on and best of all working on it with my young boys.

I would build it out of fibreglass.

What I am not sure of is the hight and shape of the pod, some seeam to be more of a hull extension while other are mounted quite high. I have heard if you don't get these measurements correct you can end up with cavitation.

Has anyone had a go at doing a pod or maybe you might have found some great links on the web that might help me out.

Cheers,

CC

Unfortunately that is an example of what I would like to do. I'd be in heaven if I could afford a boat like that.

I have been doing a lot of reading but still haven't worked-out the exact design yet however I am leaning towards the pod with swim platform/duckboard.

i put a pod on my current rebuild though no swim platform, took me a while

getting all the info because its not a common boat and as such measurements

etc were not readily available.

what i found is that you will need patience building it and that when

you make the mold up for it

1: make sure you give it at least 5 coats of wax so it pops out

2: use good plasticine to round of your edges not the cheap toyworld crap

3: use double bias on all the edges before laying the matt

i dont know how many layers of matt i used but when done it finished at 15mm on the

sides and about 20mm in all corners with a weight of 32kg giving me a positive

buoyancy of 178kg. I installed 3 stringers on the inside of it to match up with

the stringers on the inside of the boat and it was mounted to the transom

with 12 x 12mm x 100mm bolts all from inside the pod because it is a full depth unit.

This was all inspected and given thumbs up by a marine surveyor i got out to inspect

all the work because it is a full rebuild IE removal of splash well new transom

stringers - floor and modifications to the top side .I wanted it checked etc so

i could get new paper work for max motor size - weight and a new build plate

for insurance purposes.

My pod and transom have been rated at max 125Hp and 178kg
